Had same problem with SOT23 (two different PNs and Suplliers) problem was random (AVG 0,15%). Parts are RoHS but soldered by SnPb, Lead frame Plating (e3)according to IPC-J-STD609 it means Sn pure (check the label on reel), additional info, it is S

Does your paste provider recommend a TAL? For the leaded and lead-free pastes that we use, the manufacturer recommends 60 seconds above liquidous. I note that your profile shows the TAL as 30 seconds, which may not be sufficient. That said, tho

Omid, No-clean fluxes need to be used right out of the can without thinning. In the past with RA and RMA fluxes you could adjust or thin them to your desired density because they had plenty of solids up to 30%. No-Clean fluxes have a lot lower solid

No arguments there. I 100% agree that quality engineers can and do solve a lot of problems on the spot. I've nevern said "run an analysis as soon as you get a problem". The whole nine yard started with a solderability problem. In my previous product

I guess sarcasm and quick wit flies over some peoples' heads. 8 years ago (wow, that's an old post), I was poking fun at the guy, and wanted to illustrate how ridiculous it was that he spat upon our printed circuit board assemblies to simulate moist

Don't forget repairing the boards all the special tips for the small parts sounds like you might be placing BGA may need a special machine just for reparing that. some places think they need x-ray for inspecting BGA. type of paste that you going to

We got over 500,000 placements per month with two Mydatas for three consecutive months. And I want to say organized Fuji changeovers beat disorganized mydata changeovers. Even though Daxman is right that they can take a little longer to set up. In o

Panapro can be set up for the centroid data in any order. You won't be able to load the centroid data straight into the machine though. At one time I used Unicam to program a mydata. Then we got a panasonic line. The panarep said we could configure

I hope this doesn't add any confusion. I save my data as a .csv file and bring that into Cad2cad. This is how I was shown to do it by Assembleon. To use .csv you have to set your file format on the format cad file tab(during import to Cad2cad) to Cha

Thanks for the response guys! The parts are being sent to a local lab as we speak. I'll let you know the results when I get them. I am not sure the purpose of the copper band, but the black around the band is just shadowing from how I took the pi
