Lead-Free Reliability - Building It Right The First Time

Technical Library | 2008-07-01 18:59:09.0

As lead-free and RoHS compliancy fast approaches, it is more important than ever to build it right the first time. Lead-free assembly and RoHS will bring about numerous changes and the number of variables with which to contend is increasing, creating increased risk of defects and reduced product reliability. However, understanding what the variables are and their impact on the assembly can great increase product reliability.


Design and Construction Affects on PWB Reliability

Technical Library | 2012-04-26 18:52:37.0

First presented at IPC Apex Expo 2012. The reliability, as tested by thermal cycling, of printed wire boards (PWB) are established by three variables; copper quality, material robustness and design. The copper quality was most influential and could be eva

Impact of Assembly Cycles on Copper Wrap Plating

Technical Library | 2020-07-22 19:39:05.0

The PWB industry needs to complete reliability testing in order to define the minimum copper wrap plating thickness requirement for confirming the reliability of PTH structures. Predicting reliability must ensure that the failure mechanism is demonstrated as a wear-out failure mode because a plating wrap failure is unpredictable. The purpose of this study was to quantify the effects of various copper wrap plating thicknesses through IST testing followed by micro sectioning to determine the failure mechanism and identify the minimum copper wrap thickness required for a reliable PWB. Minimum copper wrap plating thickness has become an even a bigger concern since designers started designing HDI products with buried vias, microvias and through filled vias all in one design. PWBs go through multiple plating cycles requiring planarization after each plating cycle to keep the surface copper to a manageable thickness for etching. The companies started a project to study the relationship between Copper wrap plating thickness and via reliability. The project had two phases. This paper will present findings from both Phase 1 and Phase 2.

Fine Pitch Cu Pillar with Bond on Lead (BOL) Assembly Challenges for High Performance Flip Chip Package

Technical Library | 2018-01-17 22:47:02.0

Fine pitch copper (Cu) Pillar bump has been growing adoption in high performance and low-cost flip chip packages. Higher input/output (I/O) density and very fine pitch requirements are driving very small feature sizes such as small bump on a narrow pad or bond-on-lead (BOL) interconnection, while higher performance requirements are driving increased current densities, thus assembling such packages using a standard mass reflow (MR) process and maintaining its performance is a real and serious challenge. (...) In this study a comprehensive finding on the assembly challenges, package design, and reliability data will be published. Originally published in the SMTA International 2016
