SMT proofing small batch processing process

On the empty PCB board, SMT loading, and then through the DIP plug-in, etc., this entire complex process is collectively referred to as SMT proofing and small batch processing; PCBA also has a little science popularization in the previous articles, that is, printed circuit boards., It is an important electronic component, a support for electronic components, and a provider of circuit connection for electronic components. Today we mainly introduce its processing process!

SMT proofing small batch processing or PCBA processing process:
1. Single-sided surface assembly process: solder paste printing-patch-reflow soldering.
2. Double-sided appearance assembly process: A side printing solder paste-patch-reflow soldering-flip board-B side printing solder paste-patch-reflow soldering.

3. Single-sided mixed assembly (SMD and THC are on the same side): solder paste printing-patch-reflow soldering-manual plug-in (THC)-wave soldering.
4. Single-sided mixed assembly (SMD and THC are respectively on both sides of the PCB): B-side printing red glue-patch-red glue curing-flap-A side plug-in-B side wave soldering.
5. Double-sided mixed installation (THC has SMD on side A and both sides A and B): Printed solder paste on side A-patch-reflow soldering-flipping board-printed red glue on side B-patch-red glue curing-flipping Board-A side plug-in-B side wave soldering.
6. Double-sided mixed assembly (SMD and THC on both sides of A and B): Printed solder paste on side A-patch-reflow soldering-flip board-printed red glue on side B-patch-red glue curing-flip board-A Surface plug-in-B-side wave soldering-B-side plug-in is attached with computers and related products, communication products and consumer electronics.

This is the busy process in the usual SMT workshop. Every product must go through strict inspections to ensure that there are no problems with the products in the hands of every customer. It is also one of the core requirements of an excellent PCB manufacturer.
