There is a new toy I received today: a NeoDen TM-240A automatic desktop pick and place machine! I’ve kept my eyes on this baby for a quite a while, and finally decided to make a purchase last week. The shipping was very fast: DHL from China, a total

That is possibley CTE mismatch between QFN and PCB material, the thicker PCB the higher fail rate.

What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

I have been asked a very good question but have not been able to find a good answer. IPC for both PCB and PCBA refer to the X & Y dimensions to measure warp and twist but how would you determine the warp and twist for a round PCB or PCBA?

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

I am to implement PBGA, and i am looking for PCB surface finish informations. A lot of technical reports are specifing NiAu finishing because of flatness property. Because of leads shape, I though that BGA doesn't need flat pads like QFP. Is it false
