Hi, For hand placement you should see about 150-200 ppm of errors (solder, placement, values etc) on a board populated of types such as 1206, 0805, SOT, Tantalum etc. . As for solely wrong components (component at wrong location) you can usualy redu

| It seems to be that we have to much NaCl left on our assambled PCB's. | The flux we use is from cobar. They say it can not be from the flux... So what can be the reason, what kind of problem may occer when there is to much NaCl. | George, Are you

| I'm trying to get a feel for what the industry is doing with regards to collecting assembly defect data in the SMT/PWA process. Is it sampling or 100%? What are the points within the process where critical assembly defect data is collected. We run

| What to look for that causes tombstoning and the corective action. | The three biggest causes that I can think of are placement machine component picking inaccuracy, placing inaccuracy, and design design design. If your placement platform is pic

Bill, You should wipe clean. The thin layer will dry out quickly and cause other problems. Remember squeegee down stop and squeegee pressure are seperate issues. If your downstop is to low the stencil and board will flex down, after the squeegee p
