What is the part designator? A lot has to do with that. Also, is this a double sided reflow board. Perhaps you need to change your process to accept two heat cycles simultaneously. Solder thieves should work. Check the archives.

In addition to robl's suggestions, I would look at the footprint on the board to make sure it meets the recommended dimensions. Abnormal layouts, particularly when pads extend under the component too far, can be problematic both by lifting the part

Do you have the ability to add copper thieving or otherwise balance the design? We had a customer making LED boards with a terible inbalance. Some of the boards would "smile" so badly in the oven that the leading edge touched the top. They switche

Istv�n: Given a choice, I�d run second side PLCC44s at 90� to the wave. As far as thieves are concerned, I�d have two, mirror images of each other. Unlike most, these thieves are not connected to pads. They are out-side of the last pad on the sid

I am looking for some design guidelines (length, width, spacing) for solder thieves which are placed behind trailing pins of wave soldered SOICs. I'd appreciate it if some one could direct me to the appropropriate reference. Also, has any one perform

Hi Stephan, Thanks,Yes there are thieving pads on Ic's .Also the two QFP, which mention,that will be removed by modifying the design in long run ,if the results/Yields are okay as with Glue as Compared to solderpaste process. Yes you are right here,b

Copper thieves...great idea...used some just today. How about some details on the wave soldering issues? I bet there are some mega-expert super brain-e-ax on here that would love to share their lifetime learned black art. Or maybe not (kidding).

Thanks Steve.The bent we are seeing is at the location without any component .It is a small and long pcb,one side fully loaded with component .Thebother side got no component. We can manually bend the pcb at the side without the component. All the la

I have some interesting problems on my hands that some of you may know the answers to. I am currently wave soldering a through hole connector to a rigidized flexible circuit. This is a compliant pin connector that is supposed to be pressed into a h
