Hi First I think you have to analize your PCB design. Heavy weight components should be gathered on one side of PCB. As I think, if you want to reflow both sides simultaneously there might be a problem. A chance that large components will drop off

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

Is there a typical DI cleaner (washer) bath/ spray temperature? (In-line cleaner) Is there a maximum temperature? I know some parts do tend to have issues like TH electrolytic jackets shrinking. But is there any situations to be aware of? Bacteri

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

Hello everybody, engeneering came up with following problem: Considering worst case the get a temperature at a component (Resistor 0805) of 109�C and 99�C at the solderjoints. As a rule of thump I said that the max. suitable temperature for the solde

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
