So,1005/0402 and 1608/0603 are same components except last numbers are in inches. For 0402: L=.04"*25.4=1.016mm: W=.02"*25.4=0.5mm which was for component 1005 as per JIA. Am I correct?

Conversion refresher: 1 inch = 25.4 mm 1 inch = 25,400 microns 10 microns = 0.3937 mils 10 microns = 0.010 mm so 0.4mm = 400 microns and for s/n/g: 1mm = 3.240783e-20 parsecs (pc) Have some fun with that one!

You have to be careful here. The figure is expressed as placement accuracy, not process quality therefore 3 sigma does not relate to 2700 PPM defects but 2700 parts per million placed outwith 15microns (0.0006" / 0.6thou). Extrapolating the distribu

Heck no, I mean we print relatively slower on complex boards, as in 1 inch/sec (25.4mm/sec), and maybe 2 inches/sec. (51mm/sec) on less complex boards. SMT is not a bottleneck in our plant and printing never the bottleneck in SMT, so I see no need t

We're in the process of purchasing a couple new reflow ovens. The ovens that we're looking at have a standard clearance of 1.00"(25.4mm), when using the Edge Rail Conveyor. We can pay a few bucks extra in increase that to 1.5" (38.1mm). I think that

Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a

Dear Dave, Sure we can ! There are two values going around. One is 50 mg/mm2 The other one is 30 g/inch2 (30 * 1000) / (25.4 * 25.4) = 46.5 mg/mm2 So we are talking the same language. Regards, Frank J. de Klein | | | Hi, | | | We have encountered one

2 oz copper should be 2 oz per ft^2 thick. There is no relationship between thickness and copper weight due to the effect of processing. Since this is a painful way of thinking about things, ppl have reached a compromise and talk about 'nominal thick
