In the case of BGA socket, the manufacturers make it permanently attached to the motherboard during production, making upgrades quite impossible. Compact devices like laptops and mobiles have BGA sockets and thus you can’t upgrade their processors.
A CPU socket is what in which the processor can be inserted and it allows the processor to be inserted or taken out without soldering. In the case of PGA and LGA sockets, the processor can easily and effortlessly be taken in and out of the socket, and it’s also possible to change or upgrade the CPU.

Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Last week, I visit a PCBA manufacturer for our new project. They not only introduce in-circuit tester but also flying probe tester, which can both ensure the quality level. So, Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Why do you order a laser stencil?

I am looking to order a prototype PCB and all the manufactures I’ve gotten a quote from all offer to include a Laser stencil, some charge for the stencil some are given free with the board. After looking online to me it looks like the laser stencil just shows the outlines of the pads. So Why have a laser stencil? what advantages do you get from having one?
