Back in the old days, based on "The Goal" by Eliyahu Goldratt, we wanted to optimize throughput. In this ... * THE GOAL: Make more money. Increase throughput. Make more money. * Throughput is gated by the bottleneck. * Bottleneck is where the mate

Hi Ken First of all, I think you are right to point out that the uptime should be calculated on the SMD line bottleneck. But I have some comments to your posting in general: The SMD line bottleneck, you say, is always the palcement machine. This i

Hi Brandon. You should always try to optimize / "balance" your line in a way so the machine with the shortest time per placement is your bottleneck. The other machines in the line should then have a 10 - 20 sec sorter cycle time, to be able to cope

I would take the following method to start Which defect is taking the most labor time to fix. which defect is causing a bottleneck to your production. Fix the one causing the bottleneck first as it will improve your plant output and profits Then

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

Hi Brian Thank you very much for you comments, Points well taken, forgive the length of my response here, but I wanted to respond to each of your points. The Pick and Place machine �should� be the bottleneck. The reason is in my 20 years in the in

Clearly, x-ray inspection should not become a bottleneck in the production process. The concept of "signature" identification is to rapidly qualify a BGA attachment as acceptable or suspicious. If suspicious, the board is taken off line for further s

We don't currently use BGA's on any of our products. Are there other worthwhile reasons to use x-ray that would benefit enough from it to justify it economically? Also, I have heard that to put it inline can cause bottlenecks.

Nuez : u mean u put an operator to check the placement mounting of components, juz before the PCBA enters the reflow oven? how does that release the bottlenecks for efficiency rates? pls explain, coz we want to learn from your experiences. Thanks.

I totally agree, if there is a bottleneck in the process anywhere then i think it's got to be hand fit, so that shoudl be driving the demand for the rest of the process. I need to time/measure things to prove it though. Great Monday discovery! :)
