Hey folks, welcome back to the blog! Today, we’re diving deep into something absolutely critical for the reliability of almost every electronic gadget out there: BGA solder joints. You know, those tiny connections that hold complex chips onto our printed circuit boards (PCBs). Keeping them strong and free from defects like those pesky little bubbles inside the solder – we call them voids – often comes down to a surprisingly fundamental aspect: the design of the pads on the PCB.
