Russ is correct, The efficiency number, or machine operating ratio, is more relevant in a HVLM environment than a HMLV senario. I have found that in HVLM, a desirable number would be cetianly 80% plus. Low 90 is not unrealistic. One must consider

Carl, That machine looks way expensive. We found a used Fuji microscopic jig for 3500.00 It came with the master jigs and master tapes. It doesn't have all the bells and whistles, but it does exactly what it is supposed to. John, I am curious as t

Your paste manufacturer will have the best guidelines for you. Different paste types and manufacturers sometimes/usually require a little bit different setup. I would also contact your printer manufacturer. As far as stencil concerns the larger/be

Russ makes good points. Your printer supplier can give good advice on machine setup also. We know we're printing well when: * Paste at least as big in diameter as your thumb is rolling across the stencil * Paste is filling the apertures * Squeegee

Hi, to profile any type of temperature process, you should try ECD products. I'm used to work with their tool called Super M.O.L.E. Gold, wich is a data logger for six thermocouples that you can run through a reflow oven, for example, and then you c

Hi, Thanks for the info! In the software can you add solder paste specs and heat sensitive components and see where the profile sits against these fast? Measurement is the easiest part I think, but what I thinks harder is good software to analyze th

Some cracks are really obvious,straight down the middle of the capacitor.Some are slight hair line fractures which fail at ICT.In all cases seen,all cracks are through the centre of the cap.My worry is that there may be some which have fractures and
