I estimate the costs about the same but we build in batches so the wave only runs a few hours a day. We do complex boards so I think its worth it plus you have to keep the machine awhile to recoup the investment in the new nozzles. If the market gets

Bobpan ..Thanks for the 1st input Let me ask in a little more detail The controller on SMT machine will understand the X-Y positions to mount the chips/transistor based on a given centroid in gerber file---the software on machines like Fuji, Assem

"Bending nozzles" "Changing dwell times" "Navels" (!!!!!!!!!??????????) And probably not taking responsibility when the poop hits the fan cause "you're just an operator". Not knowing your boards, but estimating your time scenario, I'd say you're sol

So, your scenario is: * Lead Free Solder Paste * Lead Free Reflow Profile * RoHS Components * Non-RoHS (Sn-Pb HASL plated)PCB If that's the case, you should be just fine running your Lead-Free process. There is literature on the topic of lead

I want to thank you for your help. MPM SN's are continuous (7001 to the more current 7780's), no date included. I had already contacted MPM and their Technical Support personnel could/would not pin-point the year it was manufactured, hence the reas

O.K. The noise is happening 1-3 times per day and I have yet to be there as it happens. I will probably order the new Ball Screw for $3,000.00 There goes our Holiday turkeys! Are they any other parts that should be replaced along with it? How diff

I'm not sure what kind of marginal joint you're trying to identify, but when we went through a serious ball-in-cup problem a few years ago we tried hot & cold functional test as well as a day or two of -40/+125C thermal cycling and all were pretty po

Even if it is 300 hours, using a conservative estimate of that time being worth $20/hr the machine saved $6,000 in one month. At $6,000/month the ROI is probably no more than 1 year which is good. From what I have seen in this forum over the last c

We had some materials management brainiac insist that every component of a product had to have an exact quantity stated on the BOM so we had to weigh every board with and without paste printed. We rented a 4 place digital scale, weighed 5 of each boa

Hello everyone. I'm looking for some general information on reel counters. We are trying to tighten our inventory counts, and rather than estimate a reel we're looking into getting an accurate count via a reel counter. So first, I'm wondering what
