Description

Tubular surface wired circuit conductive pattern intelligence exposure system

Technical field

The present invention relates to a kind of conductive pattern exposure method that is contained in the printed-wiring board (PWB) in the electric-device housing, especially print the method for making of tubular sensor wiring conductive pattern and customizing messages pattern.

Background technology

The producing principle of current wiring conductive pattern and customizing messages pattern is: the nesa coating that will be produced in advance on the base plate is transferred on other base plate, meanwhile forms pattern.Photosensitive conductive film is sealed at the operation that mode on the substrate is carried out lamination according to photo-sensitive resin, and described photosensitive conductive film possesses support membrane, be arranged on this support membrane and contain the conductive layer of conducting fibre and be arranged at described photo-sensitive resin on this conductive layer; The established part of the described photo-sensitive resin on the described substrate is shone the exposure process of active ray; After peeling off described support membrane, form the developing procedure of conductive pattern by the described photo-sensitive resin development that will expose.In order to improve product yield, reduce because the capacitance difference of pattern coupling formation and the conductive layer that forms by insulation course, generally by mask on-chip layer is carried out photoscanning, the exposure by this layer forms pattern at substrate, and the direction of scanning is substantially perpendicular to the length direction of this pattern.The formation of the printing tubular sensor surface wiring circuit that prior art relates to and the generation of relevant information pattern finally depend on the quality of sensor surface dry-film resist exposure quality.Can photoresists that effects on surface carry out effective and reasonable exposure, restricting the quality of product.In the exposure process, the many factors of impact exposure, exposure process are relatively more difficult in a production run operations.The design of exposure light source system is that can exposure system make the exposed light transducer exposure effect reach one of best key point.The exposure light source system mainly comprises the content of three aspects:: (1) selects suitable light source, and its spectrum that sends and photoresists spectrum sensitivity scope are complementary.Because the spectrum sensitive interval of polyvinyl alcohol (PVA) photoresists is wider, and sensitivity is also inhomogeneous in the distribution in whole interval, in addition, photoresists have certain requirement to the illumination intensity of photosensitive region, cause that too by force excess Temperature affects exposure effect, the too weak photoresists that can not make expose fully, how to choose suitable light source and make its spectrum that sends and illumination intensity can make the photochmeical reaction in the photoresists reach maximization, and are most important to light-source system.The characteristics such as the spectrum of Different Light, energy, temperature, uniformity coefficient, diffusive are all different, so choosing of light source is a very important research contents of light-source system.(2) take rational measure in certain area, to form Uniform Illumination.Uniform Illumination is to guarantee each position exposure effect of sensor surface, the conforming factor of depth of exposure, and it is restricting the overall exposing effect of sensor.(3) the control light-source system exposure area temperature that takes reasonable measure.When exposure system was worked, exposure illumination intensity had larger requirement, and the light source power of therefore selecting is all larger, makes easily the temperature of light-source system exposure area reach a higher value.The circuit paster that the sensor surface that is exposed pastes, the scope that it has a temperature to bear, the highest can not be above 50 ℃, the polyvinyl alcohol (PVA) photoresists have the phenomenon of thermmohardening in addition, it is subjected to thermmohardening easily in the intense light source environment of high temperature, thereby make photoresists change its water soluble characteristic, affect exposure effect.The high-intensity heat that light source sends easily causes the phenomenon that is exposed the accelerated deterioration of sensor surface circuit paster, not that each light source can both meet the demands, exposure light source need to provide Uniform Illumination zone, and Uniform Illumination is a key factor of impact exposure quality.A lot of light sources can produce a large amount of ultraviolet rays, can cause the system operator infliction of body.

Requirement and the requirement of transmitter and the characteristics of transmitter output signal according to intelligence control system, intelligence control system has adopted the i-7017RC analogue collection module of ICP DAS, it has analog-digital conversion function, and can utilize the DCON agreement of deep lattice intra-company exploitation that it is carried out Long-distance Control.It can communicate with the RS-485 communication port of master controller i-7188EA by this communication port with a RS-485 communication port, realizes data acquisition, and the baud rate of serial communication can reach 115.2K.I-7017R can gather the electric current input of eight passages, and without outer meeting resistance, and inside is provided with high voltage protective, can bear the effective voltage of 240V and is not damaged.Its main performance index: sample rate is 10 times/s, sampling precision for ± 0.1%, input impedance 1M ohm, 10～30V DC power supply, power consumption 1.3W, so its characteristic index satisfies the requirement of exposure system analog acquisition fully.In the use of i-7017RC pin, first three analog acquisition passage is used for being connected with transmitter, its RS485 serial communication port (DATA+, DATA-) is connected with master controller RS485 mouth, and VS+ and GND are two pins of Power supply, is its power supply with the 24V direct supply.

Intelligence control system comprises xenon long-arc lamp, motor, contactor, display, hummer, analogue collection module i-7017RC and electrical connection analogue collection module i-7017RC illumination transmitter and two temperature transmitters that are electrically connected around master controller.For the exposure effect of the sensor that makes various models reaches best, the Design of Rotation of direct current generator be at a high speed and two grades of low speed, the switching of the power supply realization rotating speed by the switching direct current generator.For to exposure during work temperature and the illumination in the casing test, system also needs to have the function of temperature and illumination data collection, need rational man-machine interactive system to carry out man-machine conversation, therefore the man-machine interactive system 4 that comprises display and keyboard is joined in the controller periphery, display is used for display system duty and parameter, and keyboard is used for operation, simultaneously in order to adapt to operator's custom, display has the function that Chinese character shows, simultaneously keyboard operation is simply easy.System also needs to select to have the controller of Memorability, is used for preserving parameter.On the input channel of hardware system, need to gather three tunnel simulating signals, comprising two-way temperature signal and one road illumination intensity signal, have the ability of four light source switchs of control on the output channel, the simultaneously break-make of motor and the adjusting of speed also needs controlled.Therefore in the selection of core controller, its interface must meet certain requirements, and it should comprise the interface of interface, display and the keyboard communication interface, control motor break-make and the rotating speed that gather three road analog signalses and gather, the interface of control four road light source break-makes at least.Smart machine generally adopts by a plurality of key combination and consists of the button keyboard together, and a button in the keyboard all represents a specific function or numeral.Keyboard commonly used has two types of coding type and non-coding formulas.Present embodiment has adopted non-coding formula keyboard.Non-coding formula keyboard is with the closing and closing of the methods analyst key of software, and software is by periodically scanning one group of button or switch, and whether inquiry has button closed.Because the operating system flow process of intelligent exposure system is fairly simple, so the non-coding formula keyboard that use is flexible, cost is less has been adopted in the design of keyboard.

Non-coding formula keyboard is divided into again independent keyboard and matrix keyboard, and they are to divide from the different of core controller connected mode according to keyboard.In design, when generally number of keys is greater than eight, generally all adopt matrix keyboard.The characteristics of independent keyboard are that a key takies an independently interface, i.e. a key one line.When number of keys was more, this structure need to take more detection line, so independent keyboard is not easy to form large-scale keyboard.Intelligence exposure system workflow is simple, has designed 6 buttons according to system's needs, has therefore selected the keyboard structure of independent keyboard as native system.In the design of keyboard definition, in order to satisfy the requirement of systemic-function, designed six switch keys, each button all adopts common switch as the button device.System need to control rotating speed and the break-make of switch and the motor of every light source, so the operator can carry out by operation push-button the control of light source and motor.In addition, the time shutter of exposed light transducer needs the operator to arrange in advance by button, when going wrong in exposure process, can pass through button interrupt system work etc.

The display that intelligence control system adopts will directly provide various information to the operator.Display need to show that necessary information makes the operator understand the stage of system works.In the intelligent exposure system course of work, need to arrange various parameters, so display needs the display system parameter information in when work, comprise the parameter after parameter and the change before arranging.Intelligence control system can automatically be chosen the parameter that presets according to the model of exposed light transducer and carry out work, therefore needs display to have and shows various type informations and the convenient function of selecting.In the exposure course of work, need temperature and illuminance information in the real-time collection casing, the size of these two signals also will offer the user by display.The expose time and date of a collection of exposed light transducer, the information such as length of time shutter will provide the operator.Behind end exposure, display should have relevant prompting.In addition, for handled easily person operation, display also should show dependent help information.

According to systemic-function and characteristics, adopted favourable brightness dichroic liquid crystal display.The single chip circuit part of this display is roughly the same with similar LCD MODULE circuit, the display drive logic circuit then adopts special optimization logical circuit to replace special liquid crystal and drives chip, utilize time sharing to allow demonstration and input data carry out simultaneously, realized the high speed renewal of picture, and do not interfere with each other.Its physical dimension is 172 * 120.5 * 32, and it is installed in the square hole of corresponding size of human-computer interactive control box processing.Its dot matrix specification is 480 * RGB * 234, can show 14 row * 30 row Chinese characters, can satisfy the display requirement of system fully.And this display module has the function that presets the page, and it can preset 256 pages of pictures.It can show black, blue, green, blue or green, red, powder, Huang, white eight kinds of colors, and it can communicate with serial ports or parallel port, and present embodiment communicates itself and core controller i-7188EA by serial port.Its operating voltage is 12V, and the left and right view field angle is 150 degree, power 12V * 870Ma.

The external interface of display is 20 pin pins, three ground wires and three power leads are wherein arranged, all the other are the pin of serial communication port and the pin of parallel communications mouth, core controller communicates with by serial ports, communication is mainly to send data with its 14 pin RXD ports to it, and its 15 pin DTR are buffer full signal, if every group data volume is less than 256 bytes, between every group enough gaps are arranged again simultaneously, do not judge that then DTR position signal also can send continuously.Therefore, for convenient design, after display sends data, all leave the time enough gap in use at every turn, do not use this pin of DTR.In order to improve communication speed, the Configuration of baud rate of communication port is 9600bps (SW1-3 of display is allocated to the OFF position), the communication format of master controller i-7188EA and liquid crystal display is: 1 low level start bit, 8 low levels are front, high-order after data bit, 1 high level position of rest.

Consult Fig. 5.In the intelligence exposure system, needing the parts of control fewer, mainly is the control to four exposure light sources, motor and hummers, all digital output realizations by master controller to the control operation of these three parts.The control of hummer is fairly simple, hummer is serially connected between the digital output of 24V voltage terminal and master controller i-7188EA, hummer can not sounded when delivery outlet output high level, and output low level then makes hummer send the sound owing to there is pressure reduction in two ends.Therefore the duty of hummer can be controlled with state that programmed control change its control delivery outlet.

In order to satisfy the demand of modules voltage and power consumption, need to select suitable Switching Power Supply respectively they to be powered.Need the master controller i-7188EA of parts chromatic colour liquid crystal display (12V), the direct current generator (5V and 12V) of direct current supply, deep lattice and i-7017RC data acquisition module (12V～30V), relay (24V) etc.Therefore system need to provide 5V, 12V, and the DC voltage of 24V, and the voltage of 5V offers direct current generator, and maximum current is no more than 1A during work; 12V voltage need to offer direct current generator and display, and when both needed to power simultaneously, the greatest requirements electric current was no more than 2A; 24V voltage is supplied with master controller, i-7017RC data acquisition module and the relay of deep lattice.System selects the Mean well D-120A of company and S-150-24 switch power module, D-120A has 5V and 12V Voltage-output port, output power can reach 60W, maximum operating currenbt can reach 12A when namely only exporting 5V voltage, maximum operating currenbt can reach 5A when only exporting 12V voltage, the output of 24V voltage can be provided, and its output power is 150W, can satisfy the requirement of system fully.In addition, these two power modules are of a size of 199 * 110 * 50 ㎜, and weight is all at 0.82kg, and the input of alternating voltage can be 110V and 220V, can be configured by the power switch that disposes on the power module.

The light-source system of Switching Power Supply, air ejector fan and four 1500W needs the alternating voltage of 220V to power, so system adopts three-phase electricity to power.For each phase current that makes three-phase electricity is divided equally, the two-phase in the three-phase electricity is four light source power supplies, and namely every light source takies an electricity mutually, and other one is used for mutually to Switching Power Supply and all exhaust fan power supplies.The power supply of A.C. contactor control whole system is adopted in the control of forceful electric power.Contactor is a kind of robotization switch that is used for being switched on or switched off load-carrying alternating current-direct current main circuit or large volume controlled circuit, and it can not only be connected and commutation circuit, but also has the effect of low-voltage release guard.Contactor control capacity is large.It uses and is applicable to frequent operation and far distance controlled, is one of critical elements in the automatic control system.The contactor that system adopts is the CJXZ-4011 that Andeli company produces, and it adopts the contactor connection of standard to be connected with two buttons, is used for controlling the on/off of whole system.

Intelligence exposure system analog acquisition passage has adopted two temperature sensors that are connected with the 24V power supply, illuminance transducer, transmitter and an A/D converter, the output voltage signal end of temperature sensor, illuminance transducer is electrically connected with the input end of analogue collection module i-7017RC, has realized that temperature and illumination data gather accurately, timely.The intelligence exposure system comprises the relay K that is connected electrically in master controller i-7188EA, the i-7017RC analogue collection module, motor, display, keyboard, hummer, temperature sensor, illuminance transducer is electrically connected with analogue collection module i-7017RC, the Switching Power Supply that connects on the relay K circuit, fan AIR and contactor, contactor is through the continuous transmitter T1 of relay K, T2, transmitter T1, T2 is in parallel by ballast resistor L, be parallel with K switch 1 and capacitor C2 on the transmitter T2 secondary coil circuit, G is the sparking distance G that capacitor C 1 both end voltage reaches, Switching Power Supply respectively with display (12V), direct current generator (5V and 12V), the master controller i-7188EA of deep lattice and i-7017RC data acquisition module (12V～30V), relay (24V), hummer is electrically connected and they is powered.The principle of work of xenon long-arc lamp as shown in the figure.The contactor power switch that closes, the secondary coil with the transmitter T1 that boosts in the trigger circuit that relay K is electrically connected induces 3～6KV high pressure.At every half cycle of alternating voltage, secondary high pressure is to storage capacitor C1 charging, and when the C1 both end voltage reached the voltage breakdown of sparking distance G, sparking distance punctured.C1 produces the high-frequency and high-voltage spark pulse by G, and to the elementary discharge of pulse transmitter T2, secondary induction goes out 10,000 volts of above high voltage pulses.When C2 voltage reached the xenon long-arc lamp sparking voltage, the xenon in the lamp ionized rapidly, the flashing discharge.As long as trigger has the output of enough energy, make heated by electrodes to having certain heat emission ability, the gas in the fluorescent tube, then by spark discharge excessively to arc discharge, xenon lamp is lighted.Power supply is powered to xenon lamp through the ballast resistor L of main circuit.K switch 1 should be closed at this moment, to prevent large electric current the T2 secondary coil burnt out.The effect of L is to make the Comparision of lamp stable.

The A/D converter that is connected with sensor is converted to digital quantity with the analog quantity of sensor output, and this analog quantity refers generally to the voltage and current parameter.When selecting A/D converter, need to consider its resolution and the technical indicator of several keys such as quantization error, conversion accuracy, switching rate and full-scale range.The thermal resistance that is connected with A/D converter is most widely used temperature sensor on the engineering, occupies an important position in the temperature survey field.Thermal resistance sensor utilizes the temperature variant characteristic of conductor resistance to carry out temperature and measures with the parameter relevant with temperature.The major advantage of thermal resistance sensor is the measuring accuracy height, larger measurement range is being arranged aspect the low temperature, be easy to use in automatic measurement and telemeasurement.Range of temperature in the exposure system casing 1 is very little, and minimum depends on the temperature of exposure system working environment, is generally the minimum of room temperature, the highlyest is no more than 60 ℃.Therefore considered to be convenient for measuring the higher thermal resistance sensor of precision at low temperature in the selection of temperature sensor.Intelligence exposure system thermal resistance sensor can adopt the happy WZP-010 type thermal resistance temperature sensor of rising the production of robotization Science and Technology Ltd. in Chengdu, its measurement temperature is-50 ℃～350 ℃, measuring accuracy can reach 0.1 ℃, can satisfy system requirements fully.It can be supported the use with happy JWB-DP-A temperature transmitting module of rising company, temperature variation is converted to the normalized current output of 4～20mA.The temperature transmitting module that is electrically connected with thermal resistance temperature sensor is the two-wire system lead-in wire, and supply voltage is direct current 24V.About the measurement range of illumination and selecting of illuminance transducer, the illumination that generally can provide the people to read is just enough at 500～1000LUX, and the cloudy day, outdoor illumination was about 8000LUX, and the illumination under the winter sunlight is 60000～80000LUX, illumination under the summer sunlight is very strong, is about 100,000 LUX.Therefore, the maximum illumination intensity that can not surpass under the sunlight in summer of the size of illumination in the exposure casing, ZD-H-AT type illumination transmitter is adopted in the measurement of illumination, and its measurement range is 0～100000LUX, has satisfied system requirements.

Exposure light source utilizes four solid-state relays to control respectively, and four relays that are electrically connected with master controller take four digital outputs.The solid-state relay of control light source has four pins, and two is the control inputs pin, is light current energising end, and all the other two is output pin, is forceful electric power energising end.The switch of two output pins as light source is connected input pin one termination 24V power supply, the digital output of another termination master controller with light-source system.When control inputs pin two ends were applied 24V voltage, two output pins were connected and are on-state, otherwise are off-state.After the master controller initialization, the delivery outlet state of acquiescence is " 1 ", and namely high level because the solid-state relay other end connects 24V, is high level also, so does not have voltage difference between two ends that power supply can not start.When the needs power-on, only need to utilize the corresponding delivery outlet of programmed control, make its state be " 0 ", just there has been the voltage difference of 24V at the two ends of control inputs pin like this, cause the relay output end connection, and light source can start.

Xenon long-arc lamp is furnished with trigger and ballast resistor, so can utilize relay K to play the effect of light current control forceful electric power.Relay is divided into electromagnetic relay and the contactless solid-state relay that the contact is arranged, with respect to the electromagnetic relay that the contact is arranged, solid-state relay has long, the advantage such as frequency of operation is high, reliability is high, use is safe, externally electromagnetic interference (EMI) is little of life-span, so native system selects 4 solid-state relays to control respectively every light source.According to the watt level of every light source, select the relay of the SSR-H380D60 of shunke company type, this relay maximum can be by the electric current of 60A, and is furnished with heating radiator, can satisfy the requirement of 1500W power xenon long-arc lamp fully.

When the output state of first relay K 2 DO5 that control the motor break-make was high level, the contact of left side relay switched to unsettled, so motor can't be switched on and do not worked.When DO5 was output as low level, electrical power, supply voltage depended on that the relay on the right namely depends on the state of second relay K 3 DO6 that controls electrical source exchange, and DO6 is the then 5V voltage of turn on-switch power supply of high level, for low level is then connected 12V voltage.Two relays are inductive load, and to the impact of circuit, system has adopted two unilateral diodes to discharge, and plays the protective effect to circuit when preventing that relay from cutting off the power supply suddenly.

When needs start intelligent exposure system, press the button of often opening, the contactor Inside coil produces magnetic force because there being electric current to flow through, make main noddle on contactor and inner normal open switch closure, like this major loop energising, the work of intelligence exposure system, this moment, intelligent exposure system was not affected by it regardless of the button of often opening.When needs disconnect intelligent exposure system, press normally closed pushbutton switch, the relation that it is connected during by the normal open switch of adhesive with contactor inside, so its rear coil current loop that is pressed is cut off, cause the disconnection of main contact, and then cut off the power supply of system.

The core component of Software for Design is that i-7188EA is developed, and the establishment by program makes it carry out work according to fixing flow process.Working method and the common computer of i-7188EA are similar, the Mini-BIOS that the internal processes data store is divided after it is switched on starts, then operating system ROM-DOS operation, operating file CONFIG.SYS and AUTOEXEC.BAT behind the os starting just move the program (program can be write with QBASIC or C language) of the realization specific function of being write by development of user afterwards.

The program of moving among the i-7188 in the present embodiment is write by the C language, select BorlandC++3.1 as the development environment of application program, the application program that writes is compiled connection, generate executable file, put into the program storage area of i-7188 by instrument, i-7188 automatically performs this file after starting.

The design of software flow mainly has six functions: for certain model sensor setting parameter and preservation; Sensor model number Automatically invoked parameter work according to user selection; Call a front exposure parameter job; Shortcut calls exposure parameter work; Expose according to the parameter that the user arranges; Automatic decision end exposure and warning function.

System has the parameters memorizing function, can carry out light exposure test for every kind of model specification sensor, parameter can be kept in the system after drawing optimal parameter, the user need not to be concerned about exposure parameter after preserving, can directly select exposed light transducer to get model and get final product by definite, the exposure parameter that system can select to preserve automatically carry out work.Therefore, software systems not only need to design the function that the exposure sensor parameter arranges and preserves, and rational human-computer interaction interface will be provided, and are convenient to the user and carry out the parameter setting.Parameter arranges the using method with hold function: system's rear display that powers on is entered the system boot interface, this moment short any one key of upper and lower, left and right of pressing, the interface of display just is shown as the exposure model and selects the interface.Find through overtesting, the design of exposure parameter depends primarily on the length of sensor, the sensor of equal length has basically identical optimum exposure parameter, the selection of the model of therefore exposing is designed to the selection of sensor length, the exposure sensor parameter of different length is different, the length of sensor is divided into eight scopes enumerates out.Can be by pressing the model of up and down key selection sensor.After choosing the model that the exposure parameter sensor need to be set, grow by cancel key until the demonstration cross section of display is shown as the parameter setting.The method to set up of parameter can show on display, namely press up and down key selection parameters option, change the value of each parameter by right and left key, if the cancellation parameter arranges and can return the upper level interface by cancel key, parameter is pressed after setting completed and is determined that key is preserved parameter and the Returning sensor model is selected the interface, carries out after this operation exposure parameter of respective sensor and just is set up or has upgraded.

In order to make things convenient for the operation of system, Software for Design according to the sensor model number Automatically invoked parameter work of user selection, call that front exposure parameter work, a shortcut call exposure parameter work, the parameter that arranges according to the user is exposed four patterns, the user can be selected by four kinds of modes corresponding exposure parameter is set carries out work.

Sensor model number Automatically invoked parameter work according to user selection.Carry out according to the method described above parameter being preserved one by one after the optimum exposure parameter experiment draws the optimum exposure parameter for the sensor of every kind of specification.Parameter is saved rear system just can carry out exposure work according to parameter corresponding to the model specification Automatically invoked of user selection.Only the calling of this function needs to power on after display shows starting-up interface in system, and short of pressing in the key up and down makes display enter the exposure model and selects the interface, selects after the model by determining just to make system carry out work according to identical method.

Call a front exposure parameter job.When the production and processing of sensor, when often the sensor of same batch same specification being exposed, so the exposure parameter during the continuous a few task of system all is the same.For adaptive system makes things convenient for the operation of system in this case, software system design call the function of a front exposure parameter job.Namely all the exposure parameter of this task can be kept among the NVRAM after each time exposure work, when the operator selected this function to expose work, system can read parameter and carry out exposure work from NVRAM.Method of operating only needs to press definite key after the system boot interface display, and exposure system directly reads exposure parameter and carries out work.

Shortcut calls exposure parameter work.The exposure parameter of system mainly is the selection that exposure light source is opened quantity, therefore system software provides four shortcuts, four shortcuts are exactly to be designated 1,2,3,4 button, long small cup number by opening corresponding exposure light source behind each shortcut, the selection of time shutter and motor speed also is by reading the value among the NVRAM, namely adopting last motor speed and time shutter to carry out work during system works.

Expose according to the parameter that the user arranges.When sensor is carried out the optimum exposure parameter experiment exposure parameter need to be set flexibly, at this moment exposure parameter arranges by user's man-machine interface.When certain sensor is carried out exposing the first time, also need the user that each exposure parameter is set, so necessary during this function.The use of this function needs the user when the system boot interface display, presses cancel key, and at this moment the man-machine interface display parameter arrange the interface, and it is the same that this interface and the parameter that parameter setting and hold function kind are called arrange the interface, and method to set up is also in full accord.Parameter is pressed after setting completed and is determined that key just makes system enter duty, the carrying out that exposure parameter arranges according to the user.

After system entered duty, Electric Machine Control drove the sensor rotation exposure.The unlatching of quantity of light source is determined that by exposure parameter display can carry out the demonstration of current state.Software systems constantly read temperature, illumination data and are updated in the display, and display can be presented to the operator with certain display packing with exposure parameter, the Time of Day of work this moment.For the operator better understands workflow, the interface also shows the function of residue time shutter, takes out the complete sensor of exposure with reminding user in the past in the corresponding time.After time shutter finishes, the meeting acousto-optic hint user of system end exposure, man-machine interface shows " end exposure " four large sons, hummer is sounded simultaneously.Unexpected in order to prevent from the course of work occurring, can forced interruption exposure work, make the outage of light source and motor, it is consistent to stop the flow process to enter after the flow process that enters after interruption of work calls and the normal exposure end.
