Hi, I have experienced the same troubleshoots for our machines and computers, accroding to the expert who did the harmonics study our problem is created by the intense use of UPS, lights yes lights. The resultant high frequency variation in sinewave

I've never heard of a customer saying just 'we want decoupling caps'. Very interesting. In RF applications - frequencies 50MHz up into several GHz, the location of where they are put is just as important as what the value is. Decoupling caps are p

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

Hi If you don't know what these puppies are, HAVE the customer specify them. You will be MUCH Safer in the long run since if you choose the wrong value they will COME Back at YOU. He might even need a network of .1 .01 Piles of places to read; Bo

Cleaning RMA with water is bad news. It will turn your solder connections white and remove none of the RMA residues. There was a thread on removing RMA within the past two weeks on SMTnet. Check the fine SMTnet Archives. Additionally, look at M

Maintain DI water to 18 Meg Ohms resistivity. You can go down as low as 2 Meg ohms, in a pinch, but I would caution on what type of board you are running if trying to clean on 2 Meg ohm. Anything that is running an RF or high frequency circuit could

Hi I was poking around for awhile and gave up on time. With a little more I could probably find a good article. Yet here is an article that tells you a little about decoupling capacitors although really more focussed on higher values. I thought abo

Hi Rob, They want you to think that their products are subtly different & that they are not interchangeable, although they are in nearly all cases (this is different for high frequency RF design). Also your layout guys aren't going to love you wi

Get the ionic specs from your flux manufacturer, and show it to the designer. No-clean flux/solder is supposed to be low to minimal in ionic contamination, which allow the whole no-clean thing. If he needs further proof, you can have the board io

Hi Chuck We make precision analog and hybrib audio processing equipment for the radio and TV broadcast industry. We have not experienced any problems relating to no-clean reflow since the introduction of the process several years ago. It is known t
