Are you still facing this issue? Well, I am so late to get to know this. I think you first check your evaporator coil if your air conditioner is still freezing up. It has been seen that a dirty airflow coil stops the proper flow of air through it. It

Hi Dave, It may be. DI water alone will not build up residue. It can attack the finish of electro-polished (mirrored) stainless steel though. I have seen a white / chalky buildup on poly inline cleaners, usually isolated in the wash section. The

Hi!Charlie, 1.Are you retrofitting your spray fluxer in your wave soldering machine? If you are, please ensure that you have a air knife just before the preheater!Fluxe fumes tends to accumulate and that could be dangerous if your air exhaust is not

Is the oven air or nitrogen? If it is air I would suggest more exhuast to pull the flux vapors out if the oven before they can condense in the cooling. If it is a nitrogn machine that makes it a little more complicated. If the filter system is clogge

Dreamy, Adding chemistry to the wash section in a cleaner does have its advantages. It reduces the surface tension of the liquid and will remove contaminates such as fingerprints. It does however complicate the process in respect to water treatment

| We're a CM doing low volume/high mix and are considering buying from one of the two big names, TR** or Sp*******/El*********. We need saponified wash for some of our no-clean over wave; the great majority is OA from our SMT lines. Any thoughts? |

By no means clean room but pretty clean environment. We have ultrasonic air humidifiers maintaining our air at about 45 RH. I agree with you about airborne stuff attaching to electro-static. It's a mystery why it is isolated to four machine, thoug

Please explain how you would go about grounding a circuit board EOS/ESD Association Frequently Asked ESD Questions 16-Threshold Volume 26, No. 1 January/February 2010 Q. I have a customer that wants us to measure our compressed air for static. Ho

You may not be getting enough exhaust pull, so the cooling modules over temp. Try swapping blower motors to isolate that before buying one. STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unlo

One thing we did for our oven is hook it up to the compressed air system in the factory and bled in a small volume of air to create a positive pressure in the oven. The air is clean (non-oiled) and comes off the dryer. We can attain 5% RH. Remembe
