This 10 - 20% loss, is it 20% of 10 parts or 10,000? How many parts are lost from a "Perfect feeder teardown"? For example our Samsung 8mm feeders lose 8 components on 4mm pitch every time the cover is released. So if we had an 8 piece run that re

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

Hello there, We have a Panasonic MVIIC with a bad PCB camera. The amp is fine, we tested that by swapping it with the small and large parts camera. When the machine is shut down for a while and we bring it back up, it takes hours for the PCB camer

Paramjeet Singh Gill So, you underfil before cleaning. Interesting. * What is it about your underfill that prevents the OA flux from attacking the FC solder balls? * Who is the underfill fabricator and product? Getting back to your solder balling

What your asking has many variables. 1. Material: SS vs. Cast Iron. Iron is thicker. Which SS? 316, 316L 2. Pump speeds, turbulence, hours of operation directly affect equipment life. 3. Things like scraping the pots, the tunnels, impelle

IPC has this. I cannot remember which one, Here is what I do for a quick reference. square pin - add .015" to the pin dimension e.g. .025" square pin gets a .040" hole. OR if the pins are large get the max dimension )e.g. a .025" square pin has

Issue: At 60'C test PCB Fails. Operator did simulation. Use of Heat Gun to heat up the BGA to 60'C while PCB is powered and running. At 60'C BGA fails. When pressed system is back which means that something becomes open. Sent BGA for SEM and found t

Thanks Cmiller & PR, I am warmed to hear others are doing this sort of thing.......like all inovative ideas, you often stumble into them. As far as im aware the ERSA dual Pot is the only machine avaiable on the market that can do this sort of thing

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

Hey Greg, As you already pointed out yourself: unless you can do away with covertape pickup-spools (or can figure out a way to empty them without loosing tension on the covertape) your feeders will not be suitable for several consecutive splices. S
