Hello Kris, No, it's not necessary to have a nitrogen tunnel setup. A nitrogen tunnel allows a process to go the extra step in providing higher quality through less defects. I can't really speculate on it's use in contract manufacturers mainly becaus

We used to use 260+-5C (500+-10F) for Sn63, now we use 240-260C (460-480 F). You probably could get away with 232C (450F) in all cases, since there is no thermal mass to a lead being tinned. We keep our tinning temperature the same as our solder po

It wasn't that long ago that your beloved UIC was attempting to charge $20K to license a GSM. Are you saying they don't have a license fee structure any more? I bet they still do. I feel the fees charged by the SMT OEM's are justified as many are as

What kind of equipment do you have now to do the 1 off boards? Is there enough profit margin to process the 200 the same way? If not, there is not enough to justify new equipment and to outsource 200 pcs with 100% traceability requirements would

An issue just came up concerning the color of FR-4. By accident we received a prototype board that was blue. We like the looks of it but can not justify a change because it looks cool. My questions are: 1: Why are most common PCB's green? 2: What are

Yes i was looking around that site this morning and found everything i needed. Thanks to all. Basically what im trying to do is justify the expenditure of a new NO2 generator for our IC cabinets. Ours died a little while back and we have been using

Or leave it stand alone. Granted, you may not be able to inspect 100%, but you can inspect before relow, after relow (if your AOI does solder joint inspection), inspect before wave and afterwards if needed. Now how did you justify a peice of equi

Trying to convince management to buy TPSys 2.4 software upgrade for MY-12 and My15 machine. Currently running 2.2 ver. Any mydata user's out there explain how my company would benefit jumping from ver 2.2 to ver 2.4. I think the cost is $1200 per m

I sure haven't JEM. Was just trying to help determine how to justify. Funny things about those claims like barcode scan, yes they help but now you need a pronter to print barcodes, an operator to put them on, etc... So is it a help? just an exampl

I mean if you are using the same stencil for the top and bottom of a board. Thanks to everyone for the help. From what I gather, it will work when the stencil cut-outs are offset from center in the Y-axis. Doesn't work too good in the x-axis, beca
