Q1: Is it sufficent to simply put meter probes in the water to get a resistance reading? A1: No. You need a meter for the purpose. Myron-L [myronl.com] is one such company Q2: I'm very skeptical of the Culligan man as they tried to pass distilled w

Good Morning Roger, The Mirtec's can be adjusted to lower your false call rate. This can be done by reducing the matching percentage for each componnent but the result of this action is that the machine becomes less selective. If you lower them too

You need to perform process a capability study prior to putting these controls into place. Cleaning a stencil after each pass will get ugly, solvent residues remaining in apertures etc. 2D inspection is good. Change paste every hour will get very

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe

It really depends on several things. Is solder paste inspection driven from the customer? Do you have a lot of time and bodies to do solder paste inspection? Does it add value to your process? If you answered �Yes� to any of the above, then you a

Back in the mid 90s I used an SVS 3D solder paste inspection system. We used it as a stand along unit but it was an inline model. We would bring printed PCBs off the Dek 265 solder printers and check every 5 or 10 printed panels. They almost alway

Q1. What kind of labels/ink/sharpe can be used under conformal coating without disolving etc...? A1. While we're not familiar with the conformal coat you have selected, this might help. Label selection: The following chemically durable materials are

Hello WaveMaster Larry, I think you are very well knowledgeable in wave machine or process. However, I think the reason why your former company won�t listen to you is because you also never listen to your people. I think you overlooked the saying �N

We agree that the squigglie part of the section of the BGA ball looks like something other than 'hot tear.' We'd guess that it is an inclusion, but it could be a sectioning defect, as you say. We agree that the majority of occurances of hot tear are

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to
