BGA stands for Ball Grid Array. It is a style of component footprint. These footprints appear as a rectangular array of small circles – one where each “ball” of the component is attached.
There will generally be a rectangular outline around the array that corresponds to the edges of the component’s package, and probably also some silkscreen (written) information identifying the component.

I have a set of LED driving lights for motorcycle that must be wired through a ground-leg pulse width modulation dimmer. The problem is the mounting bracket for the lights is grounded, so the lamp shorts to ground through the motorcycle chassis and the PWM dimmer cant dim the lamps. How do I handle this problem?
Soms, my PCB supplier mentions about silkscreen ink when it comes to logo printing. I am curious about the types and features of different inks.
My PCB antennas fail to achieve resonance, though I have changed their length. Our new product project is obstructed due to this problem now. Are there any good solution else?
