The boards are expensive because they are your product... covered in circuitry. A 2% scrap rate costs twice as much as a 1% scrap rate. Say the parts on your consumer electronics board cost $5. A machine that makes 99% good boards and 1% bad boards

Multiple Factors that account for Scrap: During Set-Up: A percentage will not work. When setting up feeders you will normally use a certain length of populated pockets. The amount of parts this affects depends on 1.type of feeder 2.type of part

Schematics help you troubleshoot further but if you do not have the ability to power up the board, you are limited in how far you can go with your troubleshooting. One solution to this problem we have used is this: The customer agrees to pay for 99

CPk is a measure of the process variance with respect to the acceptable upper and lower limits. In your case it would be the accuracy of placement. The exact position of a chip ideally would be dead centre on the pads however in real life that positi

Hi, If a PCB board is scrapped because it contains faults that cannot be repaired or it has been damaged, we currently quarantine them for a period of time. Once this period of time has passed the boards are then disposed. Does anyone know of an

i set this up for one of nokias manufacturing plants and based it on the value of the board, caluclated the average rework times, worked out the costs of rework and costs of the board then for each type manufactured put a figure on the number of time

I was going to ask the same question. As was mentioned, it depends on the classification of product. If it's IPC Class 3, with a requirement for high reliability, I'd want the OEM manufacturer to have a defined statement on this issue for more that

My plan is to remove as much of the parts as possible and reuse them. Once removed I plan to fix the baord as well. Now have a fresh board to build too.Just about every part can be reworked these days. Even BGAS. Most boards can be redone so that

I use FCT Recovery. During the last 6 months we've been going thru a 6S mission here so we have scrapped old equipment, shelving, anything with the least little metal in it. We sent them some cardboard (by mistake), they sent that back. Now we do sen

Hello Everyone: Heat Can Be Very Damaging to Boards and well as extended oven time can cut into valuable production time. Steel Camel is testing ambient temperature drying to remove diffused and embedded moisture in PCBs. We are seeking scrap pie
