Hi Efren, We are always happy to do our best to help each other out in this forum. I can't say that i have contributed with anything valuable about Your original qeustion; except that I had some serious thoughts about some really idiot posting from "

Hi Efren, Did some simple math... - 100k units/month - 24 days/month - 16 hrs/day - 75% efficiency (ballpark questimate) You'll be looking at a line that does a bit more 50kCmp/hr with an IC/TH placer that does 3.5kCmp/hr (assuming 10 IC's /TH conn

Hi Jack, I do not know what type of machine you are using and how old is your machine. But I have this problem before using Fuji machine. There are few things cause part throw.....placment speed, feeder, pick up tolerance, part dimension tolerance,

I'm not sure if anyone mentioned the single most important factor. p.m.'s. If the nozzles are getting dirty and clogged it's not going to do a great job of picking parts up. Don't think in terms of variation. It's there it's unavoidable and undet

The most common rates of in-process cleaning (under wipe) I have encountered are once per 5 to 10 prints. But this depends a on a lot of variables. More often is typically better, but more costly in under-wipe materials. (For some more info see http:

In the past, I would normally tell out highly talented inspectors to leave the balls there. The were trapped in the flux residue and were hard to remove. Never caused a problem. But then there was an incident where someone had the bright idea to u

Wave flux, although I've seen it used successfully in my past life, is not such a good idea to use as a rework/touchup flux. Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process.

For some, not all, hand assembly, we use additional flux. We use a flux pen in certain applications and liquid flux in other applications - you can't just say switch to a flux pen, it isn't always adequate. Most flux pens are ORL0 with very low sol

I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

On Saturday the 3rd, I offloaded nearly 1200 pounds of solder from my Electrovert, did the tin purge and loaded nearly 1200 pounds of sn100c back into my solder pot. It was a hell of a job, but we got it done in 8 hours. We've been running with this
