Hi CT, The bake requirements for Moisture Sensitive Components are defined in table 4-1 of the joint IPC/JEDEC J-STD-033A (link for free download at http://www.cogiscan.com, click on MSD Knowledge Base/Introduction). Normally you pick the highest

In rework, your thermal recipe needs to better mimic the recipe that your use in your reflow oven. Oh, that and proper preheating of the board and BGA. [Yano, if you get bored fighting this, rereflowing the board is within reason.] That you are hi

Hi, It depends of your boards(are they for SMD or not) and how many boards you assemble. The process at all is like that: 1.Stencil printer - to adjust the paste 2. Pick and place machine(for your quantity) 3.Reflow oven Theese are the machines you

Hello Sam Yes we have the software, but there are several things that we need to check on. First, what caused the software that you have to get damaged? If we put more software in the drive will that also get damaged? We need to know what software

It surprises me that most of our friends have forgotten to keep updated with the latest equipment available these days! For a dream line with a "blank check" why not consider factors like speed, flexibility, changeovers, ease of operation, ease of pr

So the only difference between the "regular solderers" and the BGA people is trace repair? If that is it than you should put the pay in range with your PCB repair people. We do not pay any extra for BGA rework since all they do is wick pads (common

Hi Rob, You might want to consider changing your current procedure. Components classified MSL 4 have only a 72 hours floor life at 30C/60%RH. Even if you consider the de-rating factor (table 7-1 in J-STD-033A), at 50% this maximum exposure time wil

What you need to remember is Fuji didn't make a name for itself by building this XP platform. They're strengths are/were in their chipshooters. Don't just assume that because it's Fuji it won't have reliabilty issues. I'm not sold on this platform ye

The 10k rebuild does not need to be applied every 3-4 months as previosly stated. A cp machine that is running 100% of the time on a 24/7 basis will tack up 10k hours in 12.4 months. Now we all know that this is impossible due to parts shortages, pro
