What about motivation? What steps can be taken to insure that the workers take ESD precautions, once they have been trained?

What is the procedure for insuring that our solder is not contanimated in our wave solder process if we switch between water soluable and no clean solder. We switch between the two types on the same machine during consecutive shifts. Should the entir

Are you having any issues with other ERJ series resistors from Panasonic? Any other 2010 resistors? There is, very likely, something specific to this part/package/packaging that is causing your problems. Things to check: -Identify where the issue

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

Unfortunately this is what happens when both the buyer and seller fail to take the necessary steps to insure a used equipment deal goes smoothly. Stefen fails to inspect what he is buying. Jack.....first impressions are 90% of the "battle" to satisfy

Assuming the traces run parallel and perpendicular to each other, I'd choose one direction the traces run as "x" and the other direction for "y." Then I'd pick a unique identifier on the board to insure proper orientation. Next, I'd measure warp and

A Tips window appears everytime I visit the Forum, even though I have checked the box to insure that it doesn't reappear on the next visit! Why? Doug

I have run the 4Cs for over 8 years it has been a good little machine. We use it for placing 10 mil pitch flip chips. I buy the yearly insurance through Tyco every year.

What are your preheat rates? Try a slower ramp. A typical insurance policy is to kapton tape the gold card edge. If your problem persists, try baking the boards to drive the moisture out.

I agree with Darby, apart from that the Engineer needs a Preventive Maintenance Course on the machines. In that case it is better to have training at the machine's manufacturer premises. Reason:Obvious.....Insurance!!
