What are you placing on this equipment? If you are placing flip chips, you need to have a glass plate test system to verify your machine is accurate and repeatable. If you purchase new equipment and plan to place flip chips or ultra fine pitch, it

I am looking for some assistance with placement accuracy studies for chipshooters(Fuji CP4-Cp642) and platform machines (GSM all configurations, Siemens HS50/S25). I would like some information on companies and recommendations on process of evaluatin

I did a quick some quick searches for Accuspec and saw some links to a PCB manufacturer. Is this the same company, or do you know the #?? I am not really in the equipment evaluation mode. I am looking for a system that will assist in maintaining cap

Several points: * Consider that your Cpk is probably different for both placing large and small components. * Probably your routine placement rate SB the speed you use to monitor the accuracy of your process. * Some people use a calibrated glass test

CPH is speed, CPK is accuracy.

We are doing a field study to test the placement accuracy and calculate cpk of some machines in our plant. From previous readings, it is suggested that you buy glass board kits from Accuspec, Topline, etc. Is that the easiest/cheapest way to go abo

Have you ever tried using a vision system for measuring the part placement accuracy and then clacualting the Cpk's from these results, or do you strictly use the machine vision itself? My concern with using the machine vision is that it it is biased

Maybe this number is only for the ones that actually got placed!? Like, we had a 15% pick error rate but the ones that did make it were great! So the 1.33 CPK was in regards to what parameter/specifications? accuracy, pick error, or what?

Good afternoon, http://www.panasonic-industrial.com/ Panasonic still supports their old models. Drop them an e-mail and they will answer your question. What Cpk do you need to know? Placement accuracy I suppose. Placement accuracy depends strongly

The best way that I have found to calculate CPk for placement machines is to buy the kit that is usually provided by the manufacturer of machine. It usually consists of a glass plate and glass components that are scaled. You simply program the mach
