It’s clearly to get rid of moisture, probably to keep the steam from pushing BGAs or CSP packages off the board (maybe from moisture trapped in tented vias, micro vias or other places).

I’ve noticed that all DIP packaged devices have pins which are at an angle other than 90∘ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that?
I am a buyer in a telecom company. Recently, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
Solder paste should be stored in a refrigerator and it has an expiration date. But what exactly will go wrong when it is stored at a higher temperature or past its shelf life?
What Is PCB Fabrication PCB fabrication refers to the process of manufacturing printed circuit boards (PCBs), which are essential components in electronic devices. PCB fabrication
PCB thickness is one of the important factors to consider when manufacturing printed circuit boards, it affects the conductivity, resistance, and performance of the PCB.
Printed circuit boards (PCBs) are at the heart of electronics manufacturing. However, PCBs can sometimes experience failures due to a defect called delamination. PCB Delamination occurs
