What are the defects in PCBA solder mask design?
1. Connect the pads to the through holes. In principle, the wires between the mounting pads and the via holes should be soldered. Lack of solder mask will lead to welding defects such as less tin in solder joints, cold welding, short circuits, unsoldered joints, and tombstones. 2. The solder mas...Read more -
PCB classification, do you know how many kinds
According to the product structure, it can be divided into rigid board (hard board), flexible board (soft board), rigid flexible joint board, HDI board and package substrate. According to the number of line layer classification, PCB can be divided into single panel, double panel and multi-layer b...Read more -

Flexible circuit board welding method steps
1. Before welding, apply flux on the pad and treat it with a soldering iron to prevent the pad from being poorly tinned or oxidized, causing difficulty in soldering. Generally, the chip does not need to be treated. 2. Use tweezers to carefully place the PQFP chip on the PCB board, being careful n...Read more
