I have run 0.031 boards. One of the things you may want to look at is the speed of the oven. With 14 zones you may be going to slow with the board which could be the reason your boards are starting to bow. You might also think about adding stiffners

First off - There should be no issue with washing your OA/water soluble boards with the other customer's no clean units provided that the recipe being used has been validated to effectively clean each product. If your supplier is using a batch syste

As soon as the oven temp falls below 40 C and the RH rises above 5% then you need to consider that the floor clock will start. Long term storage of devices in an oven is not good for them as it reduced their solderability and can affect their perform

I have a very odd problem with my Fuji IP3 and was wondering if anyone can help. Any part that gets picked from the MTU will fail vision recognition. After turning on the vision trace data, I can see that the IP3 is looking for the part to be rotat

My first attempt was similiar to that. It was a straight ground trace running past the circular pads that were recieving the shocks. It was hit and miss when the arcs would occur. When I cut notches in the trace so the ground line had a point next to

In order to be able to do full prototype assembly, you will need to be able to mount and reflow a large number of different devices of differing technology. One part might be a simple QFP, another might be a .4mm pitch uBGA. If you are prototyping a

Hi, We have problems with our wave soldering process. The problem is that during the same assembly, after wave soldering, some pcb’s look not clean and other pcb’s look good. We use lead free SAC305 solder and flammable flux. We think our proces
