I'd also recommend Control Micro Systems;4420 Metric Drive; Winter Park, Florida. We've been using one of their CO2 lasers for years to put a 2D code on our PCBs. 2D will save a lot of room and I'm told you can store more data. The laser drastical

Andras, Thanks so much for putting this manual up for download! It is exactly what I needed, and if I ever run into electrical problems with my machine, the schematics will save me an expensive service call. There is also a lot of calibration info

Hi All, I ran a prototype last week with one of the above mentioned connectors on board. During Inspection post reflow we noticed a solder ball had formed at the top of each leg. We used a 5thou stencil with 10% reduction on the width but it seems

Once the HumiSeal conformal coating has been applied to the printed circuit board it is usually best to allow the material to reach a touch-dry stage, before heating the board to accelerate the cure schedule. This avoids potential problems such as bu

You probably could SMT it (standard Process)first, do your PTH and then wave solder using selective solder pallets. If you stick with your current method I would consider a mini stencil such as the ones used for BGA replacement to apply paste. This w

I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature

Henkel Loctite makes a hot melt just for this. Do a web search on Loctite Hot Melt and you can see for yourself. Material comes in a variety of ways - we use the 10 inch sticks and their glue guns specially made for the material. Works well, is fa

Has anyone been involved in SMT placement equipment capability studies? I was wondering if anyone has procured used equipment and performed capability studies on the equipment and received quality and cost benefits from the resulting data. They

Peelable solder mask works well. Hand dispense and peel off after. Paint sticks work OK, but it depends on the mfger of the paint stick. In both methods you hand apply after screen print. Your Dek can be taught pads to get by. You may have to te

You don't mention any particular IC or manufacturer or marking method. However, most IC marking is done with lasers these days. The laser actually alters the encapsulation so the only way to erase the marking is to remove the encapsulation. Otherwise
