Description
Technical field
The utility model relates to electronic product crest welding technology field, relates in particular to a kind of wave-soldering preheat temperature pick-up unit.
Background technology
The assembling of electronic product THT series is to realize reliable soldering through the crest welding technique, and the crest welding is the critical process of electronic product packaging technology process.For guaranteeing THT series assembling reliability, must each item wave-soldering technological parameter that influence welding quality in the procedure for producing be detected and control.
The pcb board that must will apply scaling powder before the crest welding carries out preheating; Impel solvent in the scaling powder volatilization, excite the activity of scaling powder, effectively remove PCB pad oxide, cleaning pcb board face, prevent that PCBA from receiving thermal shock, reducing the fusion welding surface tension when getting into crest; The degree of wetting that improves scolder and PCB pad reaches good welding effect, so the detection of preheat temperature and control are one of wave-soldering connection technology important technical parameters.
Yet the device that does not have a kind of effective detection pcb board temperature in warm in the prior art.Like application number is 200910036850.6 one Chinese patent application, design be Wave-solderinging temperature measuring device, yet this device can't truly detect and complicated operation, inconvenience to the PCBA assembly preheat temperature of practical production status.
The utility model content
The purpose of the utility model is to the problems referred to above, and a kind of wave-soldering preheat temperature pick-up unit is provided.
The purpose of the utility model realizes through following technical proposals:
A kind of wave-soldering preheat temperature pick-up unit; Comprise PCBA assembly, high temperature gummed tape, temperature thermocouple, temperature measurer; Said high temperature gummed tape is fixed in temperature thermocouple the face of weld of PCBA assembly; The temperature-sensitive contact of said temperature thermocouple contacts with PCBA assembly face, and said temperature thermocouple connects temperature measurer.
Preferably, above-mentioned temperature thermocouple is connected together by two kinds of different metallic wire bonds and forms the working end, and two ends are connected with temperature measurer in addition, forms circuit.
The beneficial effect of the utility model: accurately detect the preheat temperature of the PCBA assembly of practical production status through the said temperature pick-up unit, solved inaccuracy, do not need special pick-up unit through the temperature measuring equipment detected temperatures; Practiced thrift cost; Simultaneously the utility model is realized conveniently, operates simple and easyly, has improved detection efficiency; Intuitively read temperature, realized the visual management of technology management and control.Take simple and easy to do mode, can satisfy the production line daily process management, can promote the operability of process management process again.
