Sure, divide the amount of paste you purchased last year by the number of boards you shipped.

I am new to the community and do not know where to start.

Time Standards

Electronics Forum | Thu Oct 03 09:53:08 EDT 2002 | Jim Gryga

I am looking for a software package that can provide me with a ballpark estimate of labor time required to assemble electro-mechanical products. The inputs that I imagine would include number and size of fasteners, number of wire connections, number

Criteria for storing finished SMT assemblies, shelf-life?

Electronics Forum | Fri Sep 12 08:01:55 EDT 2008 | davef

There is no standard. On the web, you can find shelf life estimates for various types of solderability protection on bare boards. These estimates won't translate directly to the storage of assembled boards, because assembled boards [and the solderabi

I'm in univerity research on SMT assembly systems. Especialy Simulation and Optimisation using OR-Methods. We developed flexible simulation models of various assembly-machines and use them for performance estimation (Components per hour) under differ

Acceptable standards

How are you counting parts back into stock? If it is an estimation then that could be your problem. One place I worked, the stockroom estimates were usually double what the lead hand would estimate. If you are using a counter then your rate is probab

How is cycle time of SMT line (Chip shooter for ex) determined?

Electronics Forum | Wed Nov 16 10:56:43 EST 2005 | aj

The latest software packages and stopwatch will do the job but if your manager is anything like mine he wants to know straight away from the BOM. If you split the bom down between placement machines i.e. caps and resistors etc on chipshooter and ICs

SMT line validation

Electronics Forum | Thu Feb 23 02:46:16 EST 2006 | INGE

It isn't an FDA validation. I think Steve has centered the problem. I have already defined all the steps and all the procedures of the process, but now I must run X boards, Y times, through each piece of equipment (as he said before); the question is
