I could not see pictures of your board - please attach one or two. So to answer your questions: 1. wave should not overflow over your board - mostly we use pallets as carriers to protect the assembly. 2. Solder dross is caused because your wave is no

Hej back at ya Your connectors could be warping during reflow. Find out by putting a connector on a hot plate and increasing the temperature. If so, you might get away with a simple fix of rotating the board 90* on your reflow oven conveyor. If you

Key benefits for us: Labour saving - machine part of SMT line (mainly one product type, 2 shifts), so boards effectively delivered ready for the next stage, with no human interaction. Uniformity of finish - where we had a critical dimension we run

Solved!! Finally it was the CPU board, I changed this and has started running perfectly. It is my opinion that the problem coming from GPU of this board, but I will never know this. by the way, I have receive a incredible support from Julio from PFI

Are you running a no clean process, or are you washing your PCBs? One caveat with ENIG is sometimes washing with hot DI water can effect solderability later on. I would also talk to your solder technicians and see what their preference is. Some pr

LandrySMT, after monitoring the errors and considering what we replaced, I also decided to replace the Z hydra motor and encoder. That fixed our problem. I looked at your message and I agreed that the next step was to replace this part. We ran hi

WOW, thanks for the documents, this will REALLY help selection. It looks like I want the FLX2011CV, that makes it a lot easier to set up and not have to reach into the machine to load and unload boards. The machine footprint is really compact, 10 m

Almost all the people here buy boards with the metal already plated on. We are mostly assembly people. The ones you really want to talk to are PCB fab people. And if you want to look into plating PCBs, I would suggest you look up Black Pad. It hasn'

I'm having a problem getting sufficient solder reflow on a SMD part. The board design (which can't be changed) is covered in ground planes that cause a lot of uneven heat distribution. I believe heat is wicking away from the culprit part, causing t
