I tried a PCB prototype service previously called Wellpcb and was happy with the cost and lead time. From their website online PCB calculator, manufacturing 10pieces of 100 × 60mm 2 − layer PCB will cost you around $27USD.

Dial indicator on a post/base. You might need a fine point tip to get between adjascent components and the BGA. Or... if you're real fance schmancy you could use a CMM if you have one.

Guys I'm looking for a software on the web that I can use to do void measurements. I have x-ray images but unfortunately no software in the machine to be able to calculate void size. Thanks in advance for your support.

Warpage of a completed assembly is an uncommon requirement. I would ask whoever is laying that requirement on you to define how they would like you to measure it.

Hi PZ, What, sort of like this one? http://creativeelectron.com/papers/EconomicsofLEDVoiding.pdf It even has the handy calculation for the reduction in thermal performance with voiding.

Hello fellow experts! Does anyone have a SPI machine that can calculate Cpk for the solder paste height across the PCB or for selected locations? Any feedback will be appreciated.

Hello, can someone share good practise how to calculate how many percent solder paste can be applied on solder mask for better solderability (by increasing stencil aperture). In eg, aperture is increased 30 percent, could it be more? Where find this
