Thanks This error only occurred with one oven profile with the reflow zone temperature set at 270�C. Perhaps it really has to do with the exhaust pull as the oven is operating very near its temperature limit with this profile. I will check that. Tha

If you�re running chemistry in the wash, the wash temperature will be influenced by the chemical manufacturer�s recommendations. Typically, wash chemistries recommend operating temperatures between 130F and 150F. If your application is straight D

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

Sounds like your preheat temperature controllers are out of adjustment. Check your operating manual for instructions.

Wolfgang: Sounds like gluteus maximus protection time. 1 "Maximum suitable temperature for the solder joint should be half the liquidous temperature" is a good rule of thumb. Where it came from, I don�t know. One place I�ve seen it repeated is: H

Both questions will depend upon the IC specifications. Check the manufacturers recommendations for temperature specification, as well as reflow profiling. As a general rule, we don't like to rework a component more than 2 times after initial reflow

I am having problems achieving correct pre-heater temperatures with our Hollis solder wave. Our original "Verification Golden board" program uses a conveyor speed of 5ft per minute and pre-heat temps of 300, 350, 400 respectively. Our "golden Board"

Hi Lads, Thanks for all of the replies. To answer a few of your questions..... My wave is a Hollis PT500N. It has 3 zones of pre-heater rod elements. Each individual element (601195-01) is 500 watts. There are 16 elements per zone so 8 Kw per zone.
