Your tool tips are being damaged because the small x-motor is not engaging when the head is picking parts. When this happens the head overshoots and you bang the tips on the mag springs. Directly after a tip gets damaged go into the service program a

Hi folks, I've been bouncing off of MyData technical support for some time on an issue with a MyData machine. Seems that this My9 likes to skip an 0402 placement at a rate of ~ 1000/million. Profile: MyData My9 Mechanical centering Midas only

Igmar, If these parts are epoxied in place, and subsequently wave soldered, I would bet you a cup of coffee that they are cracking due to the thermal shock of the wave. Typically there is a valley or dip in the temperature after the pre-heat in the w

Dear Daniel, I assume that these components are moisture-sensitive. If they have absorbed too much moisture prior to reflow you might be experiencing popcorning. This typically shows up as a bulge over the surface of the die, in the center of the p

This type of testing is only done to verify your reflow process. It is destructive testing and should not be performed on product reaching your customer. Solder is only used to provide the electrical connection from part to board. As a metal it is
