We recently purchased an old Fuji IP-I placement machine and have been testing 8x4 feeders for 0805 parts, etc. I have opened some of the non-working feeders to replace broken pieces and have noticed that some of the feeders are completely clean ins

I take it you are talking about the older style IP feeders. If so, here is what you need to do..... Get yourself some mineral spirits,a tub you can submerse the parts in, and a couple nice paint brushes. 1.Dismantle the feeder and wash all of the

At the wave, you should collect data on the critical process parameters. The cliche being, it's better to control your process via SPC versus performing SPC on defect data. Perform a DoE to determine which variable interactions have the greatest eff

SPC was a fad of the '80's and has been mis-used by the igonorant for decades now! Doing SPC on defects is a case in point. Hell I implemented wave SPC programs before eating breakfast at 2 previous companies, and they worked great..resulting in 25

Yes, doing the DoEs on your wave to achieve optimum settings that deliver the best results on your worst board is correct method. If not clear on the process, there are still wave solder process classes out there you can attend or hire in-house. If y

Bingo! In my career, I've used Wave Solder optimizer and the WaveRIDER. Pro's and Con's to both. I did a GR&R on both as well, and WaveRIDER came out on top. The main challenge is to get the operators to use it. I've found that the operators wer

If your component meets ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires, then the problem is at your customer's operation. If the problem is at your customer's operation, it's very difficult to anal

When I started using our ESV-304 the CAD converter would crash if there was a part already in the library with an alias. With the two cameras we can only put parts from one camera in the library. And our current library would be totally useless with

I am putting together an internal oven calibration procedure. I am interested in how stringent your oven calibration process is. Really what I am putting out is a verification process and a calibration process for the event that verification should

Russ, We use a unit called a Datapaq surveyor to monitor our ovens. Its basically a unit that a data logger rides through the oven in. It has 3 thermal couples across the top and 3 across the bottom. It takes measurements the full width of the proces
