Larry, Bubba's correct. He is probably just reading it off of a jedec spec sheet. Of course it really depends on what machine you are using when pin one is being determined. Not that it matters, it should still only come in the T/R package one di

We have recently purchased equipment that would probably solve your problem. We are using 1.6mm pcb material 1/3 of which is left unscored. When the pcb is de-panelized there is no damage to any components and we have cut our break time in half.

This has come up a number of times recently and a search for intrusive reflow or pin in hole reflow will reveal several threads. Also a good resource is the link below. From what has been stated on many of these forums and my own pre-production tes

Hi Kevin, you could use a fixture for supporting the assembly. I think it�s a common solution for thin PCBs. For the design you could search the archive there are some tips on this already ( search for support, fixture, pallet ). hope this helps Wo

Hello Mark, I can�t provide any hands on feedback with 0402 packages but we are using a no clean process with 0603 devices. Here are some parameters which will affect solder balling. Stencil thickness, aperture size, paste viscosity, snap off and bot

Do both sides of that board contain larger IC's and other large components or just one side?? If just one side contains large components, try running the side with the smaller components first, and then run the other side last. If that doesn't work

Hi What is the possible cause of non-wetting of solder paste to the gold land pad. What we observed in the surface of the non-wet pad is an organic FM, and using FTIR we found out that it is a flux. It is possible that the cause of non-wetting is

I am pretty sure I am not having a problem w/porous gold or nickel that does not solder. How about electroless versus electrolytic? I thought electrolytic was for goldfingers and such applications. Can you use electrolytic plating for fine pitch a
