We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit

So, got the Topaz X up and running. It has (4)FNC nozzles on 2, 4, 6, 8, and (4)74A Nozzles on 1, 3, 5, 7. We are trying to optimize it to pick up 8 components, then move over the camera, then to the PCB and place them. In the Mount data, we load

OK, did some more testing this afternoon. First, I moved the LED’s from feeder location #23 to Feeder location 30. This is three down from the other component(#33) it is picking, so it should be able to hit them both at the same time for two of the

What i have on the original 2 problem boards is the parts next to it are SOIC8 and placed using a 125F(.125" dia) 1 of witch is close and we have to Z zone it to place the SOIC last, the others have more than .02" clearance on all sides. The other

Downhole solder suggestions, in order of preference are: * Kester Sn96.3Ag3.7. Most vendors do not stock straight tin-silver alloys, whose wallet is that fat? * SAC305 can usually be used in place of one of the copper-free tin-silver alloys in downho

What solder alloy are you using at the moment which is coming to the end of its limits ? Normally in general for safe operation of an alloy we don't like to recommend any operation temp that is higher then two thirds of the solders melt point, but th

The current discussion about solder fountains has to do with copper dissolution. Broadly, copper dissolution is the weakening of copper traces where a trace and a barrel plating intersect due a loss of the copper into the solder. Longer contact time

Have you got some experience with using laser (CO2 or fiber one) to label with barcode your PCBs ? So far I thought it is easy process but now we do tests with many PCBs covered with diffrent soldermasks and fiber laser as well as CO2 has same probl

In a previous life we burned bar-codes on PCB with a CO2 laser. Initially we placed a small white epoxy pad to burn the code into. After some experimentation we found that we could eliminate the epoxy and just burn through the soldermask and the un
