Fig. 2A and the parallel electricity that 2B is respectively the flat type bonding tool tip disjunctor for mending line equipment under water for the utility model PCB
The structural representation and close-up schematic view of pole soldering tip.
Embodiment
In order that goal of the invention of the present utility model, technical scheme and its technique effect become apparent from, below in conjunction with accompanying drawing
And embodiment, the utility model is further described.It should be appreciated that the specific reality described in this specification
Mode is applied just for the sake of explaining the utility model, is not intended to limit the utility model.
It refer to shown in Fig. 1, mend the structural representation of line equipment under water for the utility model PCB, it is included workbench
101st, head rack 102, spot welding head 103, the workpiece water pond 104 and electric resistance welding power supply 105 for placing PCB, wherein, spot welding
Head 103 is arranged on head rack 102, and workpiece water pond 104 is placed on the workbench 101 of the lower section of spot welding head 103, resistance
The weldering source of welding current 105 is electrically connected with by output cable 106 and the welding head holder 107 on spot welding head 103.In illustrated embodiment
In, parallel pole 108 is installed, the PCB109 being repaired is placed in workpiece water pond 104 on welding head holder 107.
When needing to carry out repairing printed circuit, water 110 is added to submerge the PCB109 being repaired, you can by installed in soldering tip
Parallel pole 108 on folder 107 is realized carries out underwater repair welding to the printed circuit of interruption.
Need to be described further to the utility model proposes the workpiece water pond 104 for placing PCB, the very thin (general thickness of PCB
No more than 2mm), as long as plus the depth of water about 5mm can submerge the PCB being repaired.In the present embodiment, PCB workpiece water pond 104 is using thick
5mm thin aluminum sheet, the aluminum strip that 15*15mm is inlayed in thin aluminum sheet surrounding make the workpiece water pond 104 of 650*550mm (long * is wide).
Because workpiece water pond 104 is almost with PCB sizableness, the water added is also very shallow, so when mend line operation, only need to be as movement
PCB is the same, and the travelling workpiece water pond 104 on workbench 101, the printed circuit that needs are repaired is placed under spot welding head 103
Side, you can carry out a weld repair.Certainly, in order to workpiece water pond 104 move it is more flexible, can also be in workpiece water pond 104 and work
Make that multiple balls are installed between platform 101, can be achieved with any direction of the workpiece water pond 104 on workbench 101 can be flexible
It is mobile.
Need to be further described the parallel pole 108 proposed in the utility model.Prior art is interrupted to PCB
When printed circuit is repaired, it is necessary to use the method that single welding is carried out with parallel pole, because printed circuit is very thin, its copper
The strength of connection of paper tinsel and insulated substrate is limited, is easy to traditional electric resistance welding parallel pole repairing caused by output energy is excessive
The copper foil of printed circuit is peeled off with insulated substrate.The utility model is submerged in water the PCB being repaired, under water to interruption
Printed circuit is repaired, due to the good heat conductive heat sinking function of water, it is entirely avoided with print during parallel pole progress single welding
The copper foil of brush circuit is peeled off with insulated substrate.
It should be noted that during due to being repaired with parallel pole to the printed circuit of interruption, even if interrupting printing electricity
The fracture very little (often less than 0.5mm) on road, also to carry out secondary spot welding at the both ends of tiny copper foil circuit fracture.According to this
One preferred embodiment of utility model, the utility model PCB mend the bonding tool tip disjunctor that flat type is applied in line equipment under water
Parallel electrode welding head, as shown in Fig. 2 the parallel electrode welding head of flat type bonding tool tip disjunctor includes two electrodes
201 and the cylinder parallel electrode welding head 203 that is solidly fixed of intermediate insulating layer 202, the tip of cylindrical parallel welding head of electrode 203
Make about 1.5*0.6mm (long * is wide) flat type disjunctor portion 204 in portion.The parallel electrode welding head of the disjunctor of flat type tip shown in Fig. 2 is complete
The both ends of printed circuit fracture can be covered, therefore, when the printed circuit to interruption is repaired, it is only necessary to carry out once point
Weldering can complete the repairing to interrupting printed circuit.It is pointed out that the parallel electrode welding head pair using flat type tip disjunctor
In repairing for very tiny printed circuit, it can effectively simplify technique and improve the repairing efficiency to printed circuit.
It should be noted that because the parallel electrode welding head of bonding tool tip disjunctor needs larger welding energy, if should
Printed circuit is repaired used in conventional art printed substrate, is certain to cause the copper foil of printed circuit to peel off with dielectric base,
Applied that is the parallel electrode welding head of bonding tool tip disjunctor can not be repaired in conventional art on printed circuit.The soldering tip point of flat type
Hold the welding energy needed for the parallel electrode welding head of disjunctor just bigger, only the utility model proposes PCB mend line under water and set
The parallel electrode welding head using the parallel electrode welding head of bonding tool tip disjunctor and the bonding tool tip disjunctor of flat type is possible in standby.
Also needing to illustrate, prior art is repaired with the mode of parallel pole single welding to the PCB printed circuits interrupted,
Have to using benefit tape.The benefit tape of prior art is substantially tin plating or gold-plated thin copper belt, width from 0.03-0.20mm not
Deng.Because the making that prior art mends tape has certain difficulty, therefore price is expensive, general 100 feet (about 30 meters)/volume price
About 200 yuan of RMB.The utility model proposes with the parallel electrode welding head of flat type bonding tool tip disjunctor under water to the print of interruption
Brush circuit is repaired, because the parallel electrode welding head of bonding tool tip disjunctor has the function of directly welding fine enamelled wire, completely
The benefit tape of the fine enamelled wire substitution prior art of adaptation can be used.It is well known that the price of enamel-covered wire only about above-mentioned benefit
The one 1 percent of tape price, thus the utility model PCB mend under water line equipment can substantially reduce mend line production cost.
The detailed description of embodiment of the present utility model can be seen that relative to prior art, this reality with reference to more than
PCB109 is added water to submerge in workpiece water pond 104 with new, copper foil circuit is repaired with parallel pole 108 under water, kept away
The stripping of the copper foil and insulated substrate of printed circuit is exempted from.It is proposed to apply flat type in addition, the utility model PCB mends line equipment under water
Bonding tool tip disjunctor parallel electrode welding head 108, not only realize only need spot welding can once complete to interruption printing electricity
The repairing on road, the expensive benefit tape of prior art can also be substituted with enamel-covered wire, cost can not only be saved, and can be effectively simple
Change to mend Wiring technology and improve and mend line efficiency.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned realities
The mode of applying carries out appropriate change and modification.Therefore, the utility model is not limited to specific implementation disclosed and described above
Mode, some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.
In addition, although used some specific terms in this specification, but these terms are merely for convenience of description, not to this reality
With new composition any restrictions.
