Evan, not sure if you solved it already. I wanted to mention any couplings being lose related to the motor and conveyor movement. Some have set screws that get lose with time. Also when you say manually, do you meant with a handle or you mean through

Hi, we have checked all of those and beenm in contact with heller but they said they will need to send an engineer out as they are also out of ideas, was hoping someone might've had the same issues as we have two ovens doing the same thing, wont move

Hello to all of you, I'm running some small pcb's about 2.5x3.5 inches, can somebody tell me the zone temps and speed in meters/min that I have to use to get the best solder paste shine and best quality, is an oven of 8 zones. I apreciate your suppor

Howdy Bolos, My question to you is why do you feel the need to buy new equipment? We've changed over our processes to lead free and used our existing equipment. Heller 1500 (5 zone convection reflow) Electrovert econopak (wave solder) Honestly we hav

Is that 5 top and 5 bottom zones? We use a 4 zone and a 3/4 zone oven for BGAs and have success. I don't believe that the amount of zones is the issue but what type of profile you can get out of them. I will admit that the large ovens are much eas

We are currently using 0402 resistors and capacitors in our production process. Our equipment is as follows: - DEK 265 - Siemens S25/F5 - Vitronics XPM520(5 zones) - 2% silver solder Alpha WS678 The problem is that randomly some 0402 capacitors are

There are several areas you can check. Your profile is very fast. You reach the peak at around 3 minute mark. That's not enough time for the fillet to form. Try to slow down your belt speed to around 90-95, to give it more time. Also, your temperatur

on 10 zone ovens with 3 cooling zones, my negative slope is between 2.5 to 4 deg C/second based on board size and thermal mass.
