In SMT (Surface Mount Technology) assembly, it’s common to need rework on BGA (Ball Grid Array) chips. Repairing BGA chips is not a simple task, so it’s essential to master certain techniques for BGA soldering. BGA soldering can be categorized into several methods: manual soldering using a hot air gun or a BGA rework station,…
BGA rework is typically performed to remove components that are faulty, damaged, or incorrectly aligned, and to replace them with new components. The basic principle of manual rework is to handle the circuit board and components with care to avoid overheating, which could cause damage to the board’s plated through-holes, components, and solder pads. (I…
Choosing the right brand of BGA rework station may pose a challenge for those who are new to BGA rework equipment. To select a high-quality and practical BGA rework device, it is essential to understand several factors, such as whether a three-zone or two-zone system is preferable, the size of the PCBA boards you need…
Selective wave soldering is becoming increasingly prevalent in the electronics manufacturing industry due to its ability to reduce costs, improve efficiency, and enhance the quality and reliability of electronic components.
