Consider slowing down the rate of heating during reflow to eliminate the ejactula. Well, if you feel this is caused by your customer�s design, it is repeatable, you think it�s coming from the reflow process, and you think your reflow process is well

thanks yeah we are very much looking at the reflow because the package is ceramic tough "scratch" the tape idea because the gold pad is a marking area and the surface might be contaminated and it might cause illegible marking. the slow ramp up i'll

In relation to question 2 the vacume on them is quite sensitive so as long as you bring it down slowly the component is almost sucked up off the PCB so you don't have to actually press it down on the the component, and i have never experienced any so

well as usual this for flip chip however, this application uses ceramic substrates and the nearby area in which the splatter land on is the marking area (gold pad). We cannot hide this because the package is completed bare die, meaning no heatspread

We are seeing problems with platinum over silver plated part also. Our main problem is solder splatter under these devices, and voiding at the terminations on parts off the reels.I am curious if you have removed any of these parts and noticed any spl
