Reworking fine-pitch BGA chips, typically referring to chips with adjacent BGAs spaced less than 0.5mm apart, such as Chip0201/01005 chips, presents significant challenges due to their high density. Inaccurate temperature control during rework can easily lead to damage to surrounding BGAs. So, how can we effectively remove and solder fine-pitch BGA chips? Here are the…
BGA soldering is a process used to attach BGA (Ball Grid Array) chips to circuit boards. BGA chips are characterized by having an array of solder balls arranged in a grid pattern on the bottom of the chip instead of pins around the periphery. The soldering of BGA chips presents challenges due to their unique…
