From this point of view, whether gold or silver, the purpose of the process itself is to prevent oxidation, protect the pad, so that it in the following welding process to ensure yield.
How should PCBA processing plant do a good job in component procurement: 1. PCBA component procurement channels; 2. PCBA component quality control; 3
During design, WPC can be designed according to product characteristics to reduce shadow areas and avoid collision parts.
Especially for automotive electronics, which require high stability of the product, heavy industry is not allowed, so the board after the dust removal process has become a very practical choice
These Tier 1 suppliers have decades of experience in the automotive sector, and given that they are ultimately financially responsible for reliability, they do a lot of work in modeling.
This applies not only to the interconnection and isolation of circuit boards, but also to the high frequency testing of circuit boards, because the material will change its electrical characteristics after undergoing the component welding process.
According to the welding pad surface treatment classification: organic weldability protection layer (OSP), nickel metal leaching (ENIG), nickel palladium leaching (ENEPIG), silver Immersion silver, tin immersion.
There are several repair methods that are specific to the purpose of assembly, cost, and complexity of the solder mask required to be repaired.
Keyou Circuit is a professional production of high precision multilayer circuit board, module gold circuit board, vehicle circuit board, traffic recorder,COB power supply, computer motherboard, medical circuit board.
various components (chips, resistors, capacitors, inductors, plugs, fuses, etc.) will be welded or affixed to the PCB, so that it is together with the copper foil layer. To form a complete circuit.
It is said that PCB manufacturers marketing girl is a arrived at five gourd baby, specializing in the treatment of customers with various difficult and complex diseases, professional mediation factory is not satisfied。
For different product needs, to strengthen effective quality control and maintain the due trust, we must first improve the technology, material development and overall manufacturing engineering quality control system to achieve.
