During the welding process, the PCB pad often falls off due to long welding time or multiple weldings leading to high temperature, which causes the pad copper sheet to expand repeatedly and fall off.
During my electronics career, I have been exposed to and used many welding techniques. Initially, I relied mainly on welding irons for welding work. Almost all welding tasks can be completed with a welding iron.
When designing and ordering a printed circuit board, you need to determine if you need to pay extra for welding masks and silkscreen. What is the purpose of these layers? What do they look like?
Regarding surface mount device packaging, any permeable packaging material (plastic or metal) will absorb moisture from the air. During PCBA processing, if the package is exposed to sudden high-temperature reflow soldering, the moisture will expand
PCB bending or warping can cause a host of problems. If you're lucky, the effects of the warping may be so minor that you don't even notice it. On the other hand, it may be
PCBA experts know the main benefits of automating the SMT device assembly process: reduced errors, increased yields, and consistent quality, but is automation always better? The use of SMT production line machines has become

Manual Welding In many aspects, manual welding has become almost an obsolete technique as more precise and reliable processes have been created. While hand welding was once a great technique, it has gradually declined
Abstract The structure of semiconductor materials has changed and become complex over time, so packaging also needs to evolve. To complement and handle the complexity of semiconductors, new integrated circuit SMT and through-hole DIP
Today we will certainly talk about chip inductors. In SMT chip processing, chip inductors generally play the duty of choke, decoupling, filtering, and adjusting. There are 2 primary sorts of chip inductors: winding type
In PCB design, the same oversight of the temperature requirements of PCBs will cost you more than balloons and ice cream. You need to know how much heat your PCB can withstand before it
