I have never done these components before, but if you have performed capability studies on your dispense equipment you should be able to tell if this is feasable. I can tell you that 0402 and 0201 especially 0201 requires great accuracy and volume.

The answer is yes, it is possibly a moisture-related problem. You can confirm this by baking your parts at 125C for 48 hours (ref. J-STD-033A, table 4-1). For more technical background on this issue I recommend you read the following paper : Impac

We have massive void problems on one of the BGA populated on the bottom side of the board. The board have 6 BGAs on the top and 1 on the bottom. No voids were observed during the first reflow (we reflowed bottom side first), but after the second refl

Wondering if there any CP7/F4G programmers out there that can help me out with this one. I'm assuming the setting for max and min nozzle in the "environment" section of the part data would allow me to use either the specified max OR min nozzle in th

I'm currently having issues with a 28 terminal MLP package. I have only recently started in a new company and it seems as though the manufacturers guide lines as to pad geometry do not work (at least for us). So I now have a situation where I have 4

If you eliminate this test, how would you monitor the cleanliness of your: * Bare boards * Components * Processes You probably could get a c of c from your board fab, but a c of c from the component suppliers would be burdonsome [and agruably useles

I need to address the issue for colorful display on solder joints, for whoever researched on this machine, no one can deny it is a smart feature for visual assistance. however, it is still Mono color "gray scale" algorithm. it basically "paint" the i

Hiram, We have just had the same decision to make! I was at Vitronics Soltec, Holland about 4 weeks ago doing trials for Lead Free. The Soltec Delta machine was ultimatly chosen over price verses performance. Both machines are very capable but

Other way around Dave. We decided that the Delta had more in common with the Electra rather than the Vectra, the Electra being much more expensive. For example, we wanted 3 preheat zones for lead free and this would mean an exernal fluxer unit if

Hey Dave I deal with this every day. UGH!!!! We created a Bin location for each of our pick-and-place machines. Once the parts are moved from stock the computer will be updated as SMT 01xxx, SMT 02, and SMT 03 Bin location for that part. SMT01-03 are
