RF 800 Flux ( cookson brand) - Flux acid calculation and restoration of acid value from 17 to 19

Hi, I need the RF 800 Flux Acid titration procedure and also require EPT of the same to add thinner ( RF 800 additive), i.e we are using the flux rf 800 for our wave soldering process having foam fluxer , after 2 hours we are taking sample from the

Simple question... Not so simple answer. It depends largely on process spec and honesty of the people running the test. Most will jump to throw out the flyers as "special cause". So if you didn't set the spec and didn't witness the run and measu

I want to know how you measure capacitance and resistance to 01005 components?Is there such a machine for automatic measurement of component values on PCB? We have a lot 01005 components and we lose time to measure first panel components...I'm inter

We measure each first board before the oven after every chageover...Assembling one offset and measure component, after we clear plate...We have reason why do that...But we're wasting a lot of time.So I wanted to see how you do it. Thank you for answe

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus

There's always flying probe, although it's not particularly cheap.

I'm with Steve and flying probing. As long as you are testing the capacitance of the cap in the circuit and not of the cap itself you'll get a pretty good indication. Most are going to be 10nf and 100nf decoupling caps at that size so quite easy to

Resistance value level of lead-free solder joint

Resistance: Tables of wire gauge often provide a resistance measure of some kind for each gauge. That way we can estimate the resistance of any length of wire we might be interested in. Calculating trace resistance is only slightly more complicated.

Attrition... how to measure it?

Electronics Forum | Mon Jan 30 13:19:37 EST 2012 | deanm

Now knowing that its a Quad, I'm assuming it has QuadAlign which spins the part it just picked in a beam of light and a sensor measures the length, width and height of each part. If it falls outside of a defined range, it will throw it in the dump bi

Attrition... how to measure it?

Electronics Forum | Wed Feb 15 10:37:19 EST 2012 | caerleon

The only way you will be able to measure it is to count the reel before you put it on the machine, count them when they come off and deduct the amount expected to be placed. you will then have the result of attrition on the machine. or.. Pick the p
