Hello, does anyone have any information on stress induced during V-score depaneling. We are using a machine with a fixed blade on the bottom and a free rotating blade on top driven by a motor. We have had some cracked capacitors on the edge of an a

hi Steve/Pete, Thank for your email to affirming our current mounting and soldering flow! In fact, I also don't see any problem for the pilot run(though in small volume - 500pcs). However, the problem is - I am challenged by my customer that the AI

Have anyone seen this problem: Capacitors (100nF 0805) placed on PCB and then appear cracked after reflow. After reflow, the solder joints look visualy acceptable. Then capacitors fail during testing. When attempting to remove capacitor with hot sol

We have observed Plastic BGA crack in encapsulation to substrate interface. After reflow, the device was not functioning. The Crack is observed in the fresh lot during visual inspection. What is the attachment process of package to substrate? where c

Currently experiencing a problem where the plastic molded bodies of tantalum capacitors are cracking during my SMT processing. Caught after our conformal coating process. I don't know where in the process they cracked. Currently running an exper

Has anyone had any experience with thermal shocking and cracking of SMD capacitors during the rework process? My company was advised to preheat capacitors to 125 C at a rate of 2 C/sec before replacing them onto boards. Would this maybe degrade c
