I always fix thermocouples to pcb pads across its width. Then rotate it 180 degrees to check readings. If I am happy that the oven is giving results within a few degrees C then I'll crack on and set up a soldering profile. I am not sure what the oven

Stephen, Bill, Thaks for your input. We are currently waiting for nozzles since the ones we have are badly oxidized. We do have a deoxidizing gel that we got from ERSA, not sure if it contains Adipic Acid, but it is what was suggested we used. Once

Davef, Thank you. I wonder if you have ever faced with concrete layer thickness selection for SMT shops? All I have found refers to metal treatment shops (primarily milling & drilling). 6" concrete is thick enough for them to stabilize milling machi

I'm not sure if your customer will allow it but consider sealing the perimeter of the connector where it meets the board with some kind of sealant or staking material. Cure it then apply tape on top of it. Then all you have to do is remove the tape a

#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

The pictures are kinda fuzzy so its hard to tell of the center pad is electrically connected to anything. If it's not, if its just here for mechanical stability, then you're probably fine. The other thing to make sure of is that both switches are th

Hi mates, ain't we all forgetting something? this bloke who posted this thread, has not even specified what his "stability-variation" issue is all about? defect/quality variation? downtime variation? CPH variation? etc... Just read this bloke's th

| Problem occurs because the glass transition temp for FR4 is lower than reflow temperature. Our company wrote an article which was printed in SMT magazine some years ago | that deals with this exact subject. Best way to deal with this is to use a ce

I'm hoping someone on this forum can ID this component. This is a Piccolo board used in an 8 ounce micro electric helicopter. This board has (2) 5 amp speed controls and a single rate piezo gyro to stabilize the helicopter in flight. My father's P
