Abstract
The invention discloses an adhesive brushing screen plate and a packaging method for reinforcing a computer silicon keyboard. The adhesive brushing screen plate and a key circuit board have the same shape, the adhesive brushing screen plate is divided into a hollowed part and a sheltering part, the hollowed part corresponds to an adhesive brushing part on a keyboard circuit board, and thus, adhesive material for packaging the keyboard is guaranteed; and the sheltering part corresponds to a key contact part on the keyboard circuit board and plays a role in projection for key contacts, and size of the sheltering part is slightly greater than that of the key contacts on the corresponding key circuit board. With the adhesive brushing screen plate and the packaging method for reinforcing the computer silicon keyboard, keyboard contacts can be protected effectively, conductivity of the keyboard contacts is guaranteed, the adhesive brushing screen plate can be fully used for realizing control on adhesive layer thickness and protection for the keyboard contacts, and the packaging requirement of the silicon keyboard is satisfied.
Description
Technical field
The present invention relates to Hardening Technique of Computer field, be specifically related to a kind of ruggedized computer silica gel keyboard brush coating web plate and method for packing.
Background technology
Silica gel keyboard is because of its excellent anti-adverse environment ability, extensively use in military, industry and ground observation equipment, silica gel keyboard is made up of silica gel push-button part and circuit board usually, contact placed by circuit board, on silica gel keyboard, corresponding position places conductive particle, and after button pressure, conductive particle is by contact conducting.
For ensureing the environmental suitability of silica gel keyboard and installation, usually by silica gel push-button with circuit board package together with, prevent contact oxidation and dust from entering, and high-temperature silica gel keyboard can be avoided to heave, impact operates.Traditional method puts glue on circuit boards then to be bonded together by silica gel keyboard, but some glue mode operates wayward, and quality cannot ensure, easy spilling that some glue is many is attached on conductive particle and affects electric conductivity, lacks then loosely bonding, easily come unglued.
Fig. 1 is the structural map of silica gel keyboard, and silica gel keyboard is made up of silica gel push-button film 1 and keyboard pcb 2, and keyboard pcb 2 distributes key contacts 3, and silica gel push-button presses the conducting of rear key contacts 3, key works.
Summary of the invention
The technical problem to be solved in the present invention is: operate wayward to solve silica gel keyboard encapsulation point glue mode, the problem that quality cannot ensure, the invention provides a kind of silica gel keyboard brush coating web plate and method for packing, the method is simple, highly versatile, reliable and stable, the encapsulation requirement of silica gel keyboard can be met.
The technical solution adopted in the present invention is:
A kind of ruggedized computer silica gel keyboard brush coating web plate, the shape of described brush coating web plate is suitable with button circuit board shape, brush coating web plate is divided into openwork part and shaded portions, and the brush coating position on the corresponding keyboard pcb of openwork part, ensures the sizing material needed for keypad package; Key contacts part on the corresponding keyboard pcb of shaded portions, play the effect of protection key contacts, the size of shaded portions is slightly larger than key contacts size on corresponding button circuit board.
Described brush coating web plate surrounding is provided with the fixing frame of mechanical work, can realize mechanical work, similar circuit plate welding tin cream web plate.
A kind of ruggedized computer silica gel keyboard method for packing, brush coating web plate is positioned on button circuit board and compresses, sizing material is coated on brush coating web plate, then scraper plate is compressed brush coating web plate, from side, redundant rubber stock is wiped off, take off brush coating web plate, sizing material just brush coating part can form even skim on button circuit board, finally silica gel push-button film is placed on button circuit board and compresses, leave standstill a period of time, after sizing material solidification, namely complete keypad package process.
The control of described method by selecting different brush coating web plate thickness to realize brush coating amount.
Beneficial effect of the present invention is:
Brush coating web plate is utilized to realize the even of brush coating and protect key contacts part, web plate needs the position hollow out of brush coating, during work, sizing material is coated on web plate, scraper plate is utilized redundant rubber stock to be wiped off, sizing material is layered on the brush coating position on keyboard pcb equably by the hollow out position of web plate, adopt the method can form the controlled even glue-line of thickness, and realize the brush coating of appointed part.Brush coating operation can be carried out by hand also can mechanical work.After brush coating, silica gel keyboard film is placed on button circuit board and compresses, leave standstill a period of time, after sizing material solidification, namely complete keypad package process.
The present invention effectively can protect keyboard contact, ensures its electric conductivity, can make full use of brush coating web plate and realize bondline thickness control and keyboard contact protection, meet the encapsulation requirement of silica gel keyboard.
