Problem: Flux remains on the board in the masked areas after the wave solder process. We use Multicore X32-10m no clean flux. There is no post wave cleaning. While the flux residue is not conductive, it is unsightly and it may interfere with a be

Hi Steve You really didn't tell us what is going wrong. Not enough heat to melt this hi temp solder (290C/554F)? Too much heat and burning up the pad/board? Thermo falling off? (remove all the original solder) You won't find Loctite 384 all that remo

Dave, What type of wave solder are you using? How are the t-sots oriented relative to the direction of travel? You will get the best results with them oriented with the length of the body parallel to the direction of travel. You want the leads or

Dear all, Thanks for your comment! Dave, your suggestion is very useful. I can find several good machines at there. Thanks! John, your curiosity is quite normal, as I also have no idea of the board. It is a new model. We haven't got the boards yet,

SAL, How large is the pad in relation to the solderable area on the component. I have seen similar instances where the heat sink of the component covered almost the entire bottom of the part. If your pad is the same size and the aperture is 1:1, ther

Many thanks for the name check from John Thorup PIHR can be done very simply and it can provide positive fillets on both sides of the board. I have just finished a line with SDSRS, Simultanouse Double Sided Reflow Soldering thats sodering both sides

The smt world is new to me and I have a lot of learning to do. I need some recommendations as to best way to ship partially assembled circuits. The board is question is double sided. One side is smt and the other is thru hole. Our plan is to have th

1. Verify all the part had load to machine. Get ready for the profile. 2. Run the board with double side tape. Is better to run one board for each machine. 3. Verify all the placement ( missing, misalgnment,etc )and check the value using meter for a

Brian, I agree with Jesper, You seem to have a PCB supplier problem! The conditions that you are processing your assembly with are nothing unusual and in fact very standard throughout all of the manufacturing facilities that I have been in, unless
