Kev, I looked up records of various hollis machines with 3 preheat zones. and with progressive preheat temp. of 300 400 and 500 with a speed of 3.5ft/min the topside board temp was 120C before entering the wave. the preheat elements were infrared. W

Kev, It looks like you have a preheating powerplant and you still only get the board up to 85 Deg. This indicates that the preheating is out of calibration or the range settings might be very wide (Fex the preheat elements shut down at 500 and go ba

My company is hooking up a delta max wave solder machine but we can seem to get the estop error to go away any one have a any experience with this issue.

Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Dave, There is not really a �smart� or scientific way to check this but I know of easy ways and very effective ways. Fex. an easy way to check is with a 3� spatula, you hold the spatula at the same angle as the board and drag trough the wave simula

No. It was CK who brought up AC at his home and erroneously said that having your AC on a lower setting used less power than having it turned off when you are not there. I'm saying with AC at home turn it off when you are not there and have it come

2 more statement that need consideration in the logic: 3. heating up solid solder consumes more energy than heating up molten solder. 4. keeping solid solder at a constant temperature consumes less energy then molten solder. Result: We keep our pot

WML, I won't dispute math but I will definitely point out either bad math or a missed target. In your example, you are comparing "Energy used to heat the solder and keep it warm" versus "Energy used to keep the solder warm" and fully discount the fa

The white haze is definitely an indication of moisture being trapped in uncured or improperly applied solder mask. You can verify this by heating up the board using a heat gun on an area of the board with the white haze, and if it clears up that is t

Good calculation, i have to say. Do you forgot, If you let the machine cool down during night, the rest-temperature isn't roomtemperature? right, dont you think the temperature will be something about 140�C ??? heating up time then is not 3 hours. m
