| | | | | We're running into problems with board damage (broken traces, solder shorts) due to pliers and other bizarre tools being used for depanelization. I need some sort of fixture for this. A delrin plate with a slot cut to the correct depth and

We also have a few customers that seem to buy the cheapest LEDs available and provide them for the build. We've had complete reels that had obviously been exposed and oxidized. You can try a solder with a more aggressive flux. How long is your pro

Hi I did a reflow on an HP laptop a while back- it was a DV6000 series. The original problem was the internet stopped working- turns out the south bridge chipset was causing the issue (its a very common issue I found out after searching online). Some

I assembly boards that have 200 each of the MICTOR connectors. The boards are .300" thick. I have 100% solder fill in the holes. I also have developed a rework process so I can remove and replace the connectors if the they get broken by my custome

Our engineers did a study on our medical product with 1mils standoff height, and one issue was 100% of the boards that underwent ultrasonic failed due to failure of the package wirebonding. Poor reflow control would be one area to review in any event

I worked with Fuji CP6 where one of the techs wanted a minimum of part data's. He was used to working with panasonic machines. We would get resistors broken in two if the part data was too small and parts flying off the board if the part data was t

As an alternative theory to the boards being damaged in the wave soldering process, it's possible that the panels are being handled in a way that flexes the panel and breaks the capacitors. In this possibilty, we'd expect capacitors in specific loca

Currently we measure only in schedule attainment... based on Final Assembly requirements, how many boards were produced during the week. We're working on link Final assembly requirements to be able to produce "leaner" in smaller batches, but is a pai

I'm assuming it's your x wagon tranducers that are out of synch. So the first place to start is look at your couplings on both x motors and make sure one of them isn't broken or starting to break. After that i would try swapping out your x board with

From what you explain: 1. check all movements X,Y and Z are moving free while machine is off. 2. Resit all driver cards. 3. Check interface cables or boards. Not sure if Juki is using CAN or other interface standard, but random motor errors might be
