Case details
Automotive electronics industry product characteristics and selective soldering process requirements:
Automotive boards are different from normal PCB, thick copper is the basic feature, metal base, and also ceramic base (for heat dissipation and high current, and even buried copper blocks). The temperature and current of the car board are higher than normal PCB.
Suneast Selective soldering equipment solution:
For the welding of automobile board components, it is small, high quality of solder joint and free cleaning. The free cleaning flux is selected when the flux is sprayed, by controlling the flux spraying volume, the flux can be saved about 95% and ensuring good spraying effect. The preheating module adopts segmented control and automatic temperature correction function, which can not only meet the high temperature required by the car board, but also save the power consumption of the equipment. The electromagnetic pump of solder pot can provide stable high wave, welding the solder joints and ensure high quality.
Suneast selective soldering machine for automotive board welding has the following characteristics:
1. Use small solder pot with electromagnetic pump, high wave, large flow, stable wave, deep penetration in solder points, strong infiltration and welding;
2. Nitrogen filling protection is around the nozzle and solder surface, which can improve the solderability of lead-free solder, and reduce the production of solder dross to prevent nozzle block, save welding costs and labor costs;
3. High temperature resistance, corrosion resistance, special nozzle, strong oxidation resistance, good infiltrating, and the using time is up to 3 months.
4. Automatic detection of solder level height, to ensure the stability of wave.
5. Thin solder joint.
6. Equipped with two CCD cameras which are used to monitor the welding status and PCB positioning programming.
7. Equipped with stop positioning device in the spray and welding transmission track, to ensure spray and welding accuracy.
8. The welding conveying adopts roller design, effectively prevent high temperature deformation, PCB processing edge width is much bigger than the chain structure.
9. Adopts infrared + hot air combined mixed preheating module, drawer type structure. Fast preheating, uniform temperature; fully reduce the temperature difference between large and small components, convenient maintenance.
