Under web search you type solder paste softener. It is meant to replace manual stiring process of solder paste prior use. I heard that the spinner/softener is no use as it will seperate the flux and metal content during the spinning process. But, I h

What was the original complaint? when you say solder wicked onto top of capacitor do you mean it was dewetted from the board and only on the cap? What type of device showed voiding? how bad was it 20%,50%? I have found that the paste type seems to

Wave solder - Initially high cost but after that it is relatively cheap. Selective soldering with a solder pot such as the Air-Vac PCBRM models - Much lower cost than wave but if you get the right nozzles it is a great process. Solder preforms - s

I am curious on some opinions on cleaning of boards. We have a board wash but after the wash we still need to stem them for better cleaniness. The timed steaming is prox. 2 mins a side and by the way this is a medical board. So if you got and suggest

Hi, I can give you a few steps. 1. The solder paste. Take the profile that manifacturer gives for the paste. 2. Use termocouple to measure the tempereture. Put PCB and measure the temperature in equal terms. 3. Compare your profile to manifacturers

We currently use a Universal GDM for our glue dispensing applications, piston pumps. My question is: Have you had any problems with air getting in the dispense system that will cause missing dots? If so, how have you approached to this problem? Int

Rick, my understanding is that the US do not have plan's fr lead free legislation. However the European legislation states that any product entering the european market after June 2006 must meet the lead free std's of the directive. So basically if

Hi I had to poke around awhile to see what you meant. I think you were at an advanced level where IF he knew the MSL ratings of his devices he should constrain his profile within the component mfgs tests for exposure to various profiles, or at leas
