| Is anyone aware of a good, basic Electronics assembly course? There is a manufacturing project leader in my company that needs to get some good exposure ... quickly. He is particularly interested in design for manufacturing. | Mike, You can also

Your research is on track. NC flux needs to reach activation temperature. Also, do not depend on the corrosion characteristics associated with the flux classification (ie, L1, L0, M1, M0, etc.), until the flux is activated by exposure to soldering

Sorry so late in getting into this tehcnical issue. I have seen this condition before...90% of the time in conditions of adhesion on a water soluble material... is the paste...exposure time, lot issue, etc..basically the paste's carriers and binders

I know when I worked on a NASA site, anyone in the lab was given a free physical once a year. This way they could find out what employees were normally exposed to and could track any potential illnesses. What are the costs of a lawsuit when an empl

Hi I had to poke around awhile to see what you meant. I think you were at an advanced level where IF he knew the MSL ratings of his devices he should constrain his profile within the component mfgs tests for exposure to various profiles, or at leas

As the traqnsistion to Pb free manufacturing gains speed and exposure the period between true Pb free solutions and the present is still somewhat distant. Are there any publications or documentation on the use of Pb free components and non-Pb free

You may check with the TDS of respective "active parts" IC manufacturers for their recommended no. of thermal cycles permissible in the reflow process. Last I checked 3 cycles for our RF-apps IC was still allowed. For 48pin-QFPs this can be allowed

Two BGA replacements (same location) and throw the card away is the rule we are following. Experience has taught us that anything beyond this and you'd be pushing it - specifically when your new PBGA's price is above $20.00. The biggest concern is
