Is this a new assembly/new test fixture/program? Or is this an existing assembly that is suddenly exhibiting this failure? Capacitors measured in circuit will not necessarily measure their correct values. Active components in circuit will be affec

We recently had one of our older machines ( DEK 265GSX built in 1996 ) begin to have a problem of shutting itself down without warning, after checking out whatever I knew to try and find the cause, I pulled out the Y3 enclosure and removed all the ca

We have a Heller 1707EXL that we use for lead and lead-free production. It has both a mesh belt and edge rails. We run 90% of our assemblies on the mesh belt (leaving the edge rails wide open). I have noticed when profiling a board on the mesh bel

Thermal profiling typically requires a profiling kit, this will include a thermally insulated datalogger that follows your PCB through the oven connected to a number of thermocouples which you might affix to your PCB using heat resistant tape or usin

It is sort of a self answering question if you come in from the solder paste angle. First....start gathering data. Check every day, or every new paste jar, for: Storage conditions (temp), paste expiration date, ambient temp and humidity where yo

Hi Sam, I have a feeling that what you're trying to communicate is that your DPAK's are skewing off the pad during reflow. This is caused by a thermal "mismatch" where the solder paste on one side of the DPAK becomes molten before the other, then th

Sorry, I don not know what Emerald Advisor. I looked on three of our station computers hard drives and was not able to find it. The last text line on our MC computer reads "system is setup ... enable task loader", minor difference from yours but I

I tend to get issue on and off with the feeders either stalling and/or running slow/noisy. They are actually pretty easy to clean and maintain. If you take off the side panel of the feeder you will see a few gears, belts and a motor. The first thin

As Evitomov says, provided you check everything is setup correctly there should be no issue. There can be some variation between manufacturers as to how they package certain components. For example 2512 resistors are usually in 12mm tape with a 4mm s

At the moment we do it like this: We get .csv or .txt pick and place file and .csv or excel bom file. Then I verify every single placement manualy with BOM and delete placements that are not listed on BOM. (Yes, you are right, I do it for 30 placeme
