Jigo, We have never had a need to do internal testing on solder paste, and your paste supplier should be able to tell you what the correct operating temperature range is. All of the big names in solder paste have tight quality control and I suspect t

Dear Hussman We use automatic machines on mounting PHILIPS and though quality and velocity of their mounting are very good, the girls occupied with quality control can not on 100 % to check quality of the soldering FLIP CHIP and BGA!!! Pavel

Hello, 1. I have DC engine of car's wishers with I use in at my project. the Engine specification is 12V DC 1.5A. The input voltage is constat of 12V. The problem with adding resistor ( in order to pull down the current)in the circuit is that resist

Hello, 1st of all thank you. 2. While I was reducing the rottor speed, I've noticed that the engine don't stop immidietly when I disconnect the voltage source. That makes me problem how to control what is the rottor location-How can I fix it up? 3. I

Hi, Yes you can use a PWM (Pulse Width Modulator). This is much more efficient than a large resistor & gives you good control. Here is a sample for 12V motor control: http://www.homepower.com/files/pwmhp75.pdf

Hmmm.... We use our placement data from our placement machines. Gives us nuber of placements, yield of good placements and a ton of other stuff that makes our QC peoples eyes get very very big! We use Panasonic equipment ond utilize the Pana-Pro s

Hello Everyone, For QC purposes, there are a couple of methods to both qaulitatively and quantitatively inspect your manufacturing process. For Paste inspcetion, an inline machine like the SE300 by CyberOptics may be appropriate. You may also inco

Sorry that I'm so late responding. Your new additon probably has 'backee stains on the floor already. Assuming we're talking about a fairly standard board assembly area, you don't need to specify air quality. 1 We specify * Particulate: Level to b
