2, THT process: plug-in technology, is a kind of electronic components will be inserted into the circuit board hole process. THT process needs manual operation, low productivity, but can be used for the production of some of the higher quality requirements of the product, such as avionics, medical equipment.
3, COB process: chip paste technology, is a chip directly pasted on the circuit board process. COB process can greatly reduce the size of the product, improve product performance and reliability, commonly used in the production of micro-electronic products, such as watches, MP3 and so on.
