A "quick and dirty" method would be to start tracking your assembly time per job. Divide by the number of PCBs built, divide again by the number of components per board. This should give you an average placement time per part. You can then use this n

Hi Don, record the time from when board one has exited to when board two gets to the same point (this is your total cycle time including transferring in/out, fiducial checks etc). You can then multiply this out per hour. I would suggest you want to t

Dear All During SMT process, some Tant caps were fell down without touching Epoxy . I found the problematic Tant Termanations were bended with gap. So I called to Vender and expalined this gap but the answer was the gap was within their standard and

Im trying to get the XY data to program the SMT machines. since i dont have the file, im trying to convert it from the gerber drawing. the closest one to represent the component placement is the solder pad. ive tried using linkcad to convert it to XY

My shareware program will generate a TPSys program from a Protel file, any thing from Autotrax to Altium Designer. You can download it from http://users.tpg.com.au/sarason/index.html The TPSys option is entered on the second tab dialog "Option" un

I have had similar problems before where the machine will intermittently stop with a limit error. Reset the machine and away it goes. Replacing the ribbon cable that runs from the head (37 pin D-sub)has solved this problem. This cable gets flexed a l

The ribbon cable would be my guess. I ran a IVc for about 3 years and we use to have to change out our cable at least once per year. I also wanted to add that you can contact Precision Placement Machines (PPM) for parts and service. We use to use

ROSE has the advantage in that it does have a specific acceptance criteria (J-STD-001), whereas the IC does not. ROSE allows the test to be run at ambient or at an elevated temp, IC requires the component/board/assembly to be "cooked" for 1 hour @ 8

Hi. I've been looking for SMT machines and have a budget close to 100k total on a stencil printer, p&p + feeders and reflow owen. Witch machines would you choose with this budget? Have any one of you heard of evest? http://www.evest.com.tw/product.h

Hello all lets see you are wanting to place 60,000 parts a day make sure you derate the machines you are looking at to about half of what they claim and your change over will take some time as well we do several change overs each day up to six tim
