PCB Warpage in Reflow

Electronics Forum | Thu Jul 12 20:20:31 EDT 2007 | seankim10

I�m having problem with PCB with 16mil thickness due to warpage. the board convex up in the middle after 1st reflow. It seams the warpage is caused by CTE mismatch between PCB and multiple TSOP's, which are covering ~80% of the bottom side board area

Practical Components Helps Diagnose and Treat Head-in-Pillow Failure PBGA 928-HiP — A large component with a single small die is a recipe for HiP failure

Industry News | 2012-06-01 09:09:55.0

Head-in-Pillow (HiP) soldering defects are common with modern SMT component placement. As a result, Practical Components has introduced the PBGA 928-HiP, a component that is designed specifically to be susceptible to HiP defects. It features a large 4x4 body size, 928 balls and a single small die that has a propensity toward the ball-in-socket HiP soldering defect.

Dam and Fill Encapsulation for Microelectronic Packages

Technical Library | 1999-08-27 09:29:49.0

Contract packaging houses have to contend with a large mix of die types and products. Flexibility and quick turnaround of package types is a must in this industry. Traditional methods of die encapsulation, (i.e., use of transfer-molding techniques), are only cost effective when producing a large number of components. Liquid encapsulants now provide similar levels of reliability1, and are cost effective...


Reflow Soldering Processes and Troubleshooting: SMT, BGA, CSP and Flip Chip Technologies

Technical Library | 2021-01-03 19:24:52.0

Reflow soldering is the primary method for interconnecting surface mount technology (SMT) applications. Successful implementation of this process depends on whether a low defect rate can be achieved. In general, defects often can be attributed to causes rooted in all three aspects, including materials, processes, and designs. Troubleshooting of reflow soldering requires identification and elimination of root causes. Where correcting these causes may be beyond the reach of manufacturers, further optimizing the other relevant factors becomes the next best option in order to minimize the defect rate.
