pretty sure it does squeegie blades first....then if you have a table...it drops and starts to move out.....and then the head moves. Most times i have seen this....if nothing is moving....one of the cover switches are not made...use a magnet on each

I'm curious about what you guys do for Pb-free HASL profiling. We seldom see this finish (only on consigned boards or if they specify it directly, which is very rare) so we don't have a lot of experience. Certainly we get better results with high

#1) Is the card in panel form: (Y)/(N) #2) PCB thickness: Thin card: YES, Thick card: See above. #3) is the PCB warping during reflow? (Y)/(N) #4) Is the PCB Symmetrical is shape & size? These are just some of the questions you need to ask yourse

Hello! Don, Yes, if the carrier is steel/stainless, it would be very hot when it comes out from oven. I heard that durostone (synthetic stone) carrier can meet your requirement, it can stand high temperature with low thermal transmission. So when it

We started getting better reflow after rotating the pcb to locate the greater mass closer to the center of the oven. However we still leave space between panels on the conveyor to achieve a better reflow. This costs us production time. I'm simply lo

From what I understand, in the PCB Info window that first pops up when you open CEditor, the number of fids is multiplied by the number of arrays. So if you have a 4-up panel and you enter No. of Arrays = 4 and No. of fids = 2, the machine will look

Hi, I have a SMD radio module that has castellated Pads along one edge of the module. The pick and place machine appears to place them very well but when the boards come out of the reflow oven then up to 20% of them have either rotated a few degrees

It's all about temperature versus time. The longer the over IE more zones the faster you can run. That doesn't seem to be the case for you so a 5 zone running a little slower will work. What many forget is that oven manufacturers can recommend what w
