Hi Guys, We have a customer who is requesting us to issue a document ECN (engineering change notification) record to them, IF we have any changes in : 1) direct materials used, 2) indirect materials used, 3) machine configuration, 4) change in SMT L

No problem. Your buyer knows what she should order from the BOM. If she can�t order that, she submits an alternate part approval request to the customer early in the order cycle. If the supplier sends the wrong part: it�s rejected at incoming, get

If you don't already have one, the best investment you can make in your case is a good thermometer/humidity meter. They are not at all expensive. Then record the temperature and RH about 4 times a shift. After a few weeks (maybe sooner) you can se

Folks, I'm working on setting up an automated process which captures data on SMT component dispensing during placement. Ultimately, I'm hoping to use it to account for component attrition (load/unload losses, vision/mechanical/electrical inspection

Hello everyone out there in the SMT world. I have a dilema I'm currently running a board that has 3 csp's with a .75 mm. ball pitch and .3mm ball size. And 2 qfp's-160. The stencil is 4 mils thick and I'm using a 63/37 solder paste. My reflow prof

Hi, You can't void of loose parts. But can reduce. You can ask your Lead operator or the the person in charge for that individual line to keep track on the hourly monitor. If they tracking the number of PCB went thru the machine (getting the coun

I would have to disagree on this. My experience is that you should never justify capital expediture based on just the obvious up front costs alone. There is no mention of risk of recall, warranty costs, scrap costs,and so on. Which you may get from a

Hi, I would immediately go out and purchase a profiler as you will save the cost of it on rework savings. We use a SlimKIC, and the software with it's so good it will let you adjust the oven temps to make your profile fit your paste specifications

It looks like there's another one or two threads somewhat similar, but allow me to pose another. We've only about two years experience in SMD production, and we're just starting to really ramp-up. As we stand right now, I'm not recieving informatio

Hi Matt, Get definitive answers! Contamination on the HASL finish?: From the pix you posted, it looks like something fishy is going on. I�d reject them back to the board house and demand an answer. Most board houses and purchasing people will g
