Another thing to consider - If you're processing lead free, the nickel layer between the copper and gold provides extra protection against copper dissolution. This is a nice piece of insurance especially when performing rework. Cheers

Our machine is YAMAHA YVL88II and the issues we have with these data switches are either not being picked up from the feeder at all or are being ped before assembly.

I also use Flexa but we use QP3 and our vision number is 20. I would feel they are comparable libriares.

hi manuel, you can try vision 180 frontlight. treat DPAK as two leaded part. assign the the upper and lower leads at 1 and 3.

Thanks ! I will try your recommendations, about the flux and the preheaters, yes they seems to be ok I will bring down de conveyor speed because it looks like if it is to fast is set to 3.6ft thanks again!

Armando, Make sure chip wave is pumping evenly across. These TD machines require a lot of maintenance (deep cleaning)to ensure all the holes on nozzle are open... My two cents, George

Check that you are getting an even spray pattern from the fluxer.Check that the chip wave nozzle is clean and if possible feed the PCB in to the wavesolder unit at 90 � or 180�.

You're talking equipment classification. We're not sure what your component supplier means. What do they say?
Electronics Forum | Thu Jun 04 11:10:23 EDT 2009 | leemeyer
Are you refering to components or assemblies. Assemblies are classified as 1,2 or 3 per IPC-A-610. Components are classified 1 - 6 for moisture sensitivity per J-STD-020
