Does anyone know a formula for determining my "Excess Capacity"? I know my machine's up AND down time, the effective placement rate, and my idle time. If my manager asks me what out "excess capacity" is, how do I use my "knowns" and calculate an ac

Hi Has anyone managed to accurately produce a spreadsheet or formula that will accurately calculate the amount of boards your SMT line will produce an hour. I work in a high mix low volume industry and we are constantly taking on new jobs but have n

So, to really get reliable pickup rates from new bulk feeders, I just need to replace all the chip shooters we have with more recent ones with pickup correction capability. So where is the saving? ;-) -Upside down resistors? not an issue. so what if

HI, We have placed with both Fuji Qp's and Universal Gsm's. We are running a small coil now on a Gsm with a sucessful rate.The Qp done well also, but the product is not ran on a Qp line, so no true production rate has been determined.I don't feel

Dear Dreamsniper, A big hidden cost in any cleaning system is the cost of diminished production and rework. I assume you are cleaning the adhesive stencils manually since there is no equipment cost in your formula. Manual cleaning of adhesive sten

Heyz...at this rate i'am losing my mind too! We have been doing the "looks good; look bad" approach, and backed it all up with Z-height paste measurements. Only thing there's this customer QA asking how we established those USL & LSL utilized in our

Like most things - "it depends". There just isn't a simple formula for applying general air exchange rates. Your baseline should be doing some air quality (industrial hygiene) testing to see what types of exposures the workers have. THEN, you can

Don't know if you can do it on a MyData, but I have found that I lower the rate of failed pickups on our machine by altering the placement order of devices. Specifically insisting it does not attempt to pick sequential parts from the same lane. Of co

Those Panasonic machines should be able to tell ya pick-up rates form the feeders and shape code errors (components it doesn't recognize). You will probably get a more pick-up errors than anything else. Most of this is due to plastic tape versus pa
