If you know you have cleaned any flux residues that were under there you could consider a bead of an electronic grade RTV, such as RTV3145. If you trap any uncleaned residues under there you could have long term reliability problems. But, like Dave

Hello, Can anyone comment on the implications of small sodler balls under a leadless device such as LLP with a centre thermal land. I believe that we did not make a good reduction and the paste squeezed out of the centre land and balled up under the

Hi Steve, I agree with you that cleaning under LCC's is often difficult but its not impossible. In order to clean the residues, the most important thing to consider is the right compatibility of the fluxes with the cleaning chemistry. There are seve

Hello all, we use a reflow oven from Rehm in our SMT production. At the moment we solder under nitrogen atmosphere (approx. 500ppm). Now we want to reduce the nitrogen consumption (costs etc.). What consequences can occur here? Especially on the s
