SMT technical advantages
1. The world's leading ultra-high speed rotating head productivity
Yamaha's ultra-high speed combined patch machine YSM40R uses the revolutionary synchronous pickup mechanism pioneered in the industry to enable the new development of the ultra-high speed RS head, which can be picked up in half the time of traditional rotating heads. Thanks to the adoption of the new model algorithm, the servo motor control and ZS feeder speed are faster, and due to the new multi-camera recognition speed is faster, the magnetic head reaches the world's fastest 200,000 cph, with four packs and four heads. This remarkable innovative production capability is packaged into a compact design with a width of 1 meter, achieving the highest area and line length in the world.
2.Yamaha mounters are equipped with high precision and high quality microchip mounting.
Yamaha ultra-high speed combined injection molding machine YSM40R gets stronger suction through high performance vacuum pump, making picking performance more stable and reliable.
SMT
SMT patch processing will purchase components according to BOM, BOM provided by customers and confirm the PMC plan of production. After the preparatory work is completed, we will start SMT programming, manufacture laser steel mesh and solder paste printing according to the SMT process.
The components will be mounted on the circuit board through SMT mounter, and online AOI automatic optical detection will be carried out if necessary. After testing, the perfect reflow furnace temperature curve is set to let the circuit board flow through reflow welding.
After the necessary IPQC inspection, the DIP material can then be passed through the circuit board using the DIP process and then through wave soldering. Then it is time to carry out the necessary post-furnace process.
After all the above processes are completed, QA will conduct a comprehensive test to ensure product quality.
DIP
1,The process of DIP processing is: putting in the hole →AOI→ wave soldering → cutting pin →AOI→ correction → washing → quality inspection.
2,After wave soldering, The products will be will scanned by AOI equipment to ensure that no error occurs.
