Preventing Production Defects and Product Failures


Reading time ( words)

By Dr. Jennie S. Hwang, Ph.D., D.Sc. CEO & Principal, H-Technologies Group & Board Trustee & Distinguished Adj. Professor, Case Western Reserve University

Under today’s manufacturing and market environment, the effort to maximize production yield, reduce cost and assure product reliability is becoming increasingly important to a company’s competitiveness. Considering the new and anticipated developments in packaging and assembly and with the goal of achieving high yield and reliability in mind, the “how-to” prevent prevailing production defects and product reliability issues through an understanding of potential causes is a necessity.

On Thursday, March 17, 2016, from 9:00 am to 12:00 pm, professional development course (PD21) at IPC APEX EXPO will be held at the Las Vegas Conference Center. The course will address the top six production defects and issues:

  • PCB pad cratering (vs. pad lifting)
  • BGA head-on-pillow defect
  • open or insufficient solder joints
  • copper dissolution issues
  • lead-free through-hole barrel filling
  • PCB black-pad issues

The course provides a holistic overview of product reliability including the important roles of materials, processes and testing/service conditions, as well as the crucial principles behind the product reliability. The course addresses the most prevalent production issues and defects that affect yield, cost and reliability, suitable to all who are involved with or interested in SnPb and Pb-free manufacturing including designers, engineers, researchers, managers and business decision makers; also is designed for those who desire the broad-based information.

Specific defects associated with BTCs and PoPs and the reliability of BTC and PoP assembly will also be outlined.

The main topics to be covered in this course are listed below. You are most welcome to bring your questions and issues for solutions and discussions.

Main Topics:

  • Premise of production defects and product failure prevention
  • The most common production defects/ issues in lead-free assembly
  • PCB pad cratering (vs. pad lifting) — causes and solutions
  • BGA head-on-pillow defect — causes, factors, remedies
  • Open or insufficient solder Joints – different sources, best practices
  • Copper dissolution — process factors, impact on through-hole joint reliability, mitigation
  • Lead-free through-hole barrel filling — material, process and solder joint integrity
  • PCB black-pad issues – causes, remedies
  • Defects of BTC solder joints – prevention and remedies
  • Defects of PoP solder joints – prevention and remedies
  • Product reliability – principles
  • Product reliability – roles of solder joint, PCB and component considerations
  • Summary – production defects
  • Summary – product reliability

Optimizing Test Engineering Practices for High-Mix Electronics Manufacturing

08/01/2022 | Mark Laing, Siemens Digital Industries Software
For PCB and assembly manufacturers, test engineering has become a critical factor in enhancing the profitability of new product introductions (NPIs). Given the trend toward high-mix, low-volume production, the journey from design data to an automated PCB testing program must be quicker and more efficient than ever before. In this article, we will discuss how to optimize the efficiency of the test engineering process in accordance with these new market realities.

Mining for Metals Requires a Long View

06/15/2022 | Nolan Johnson, I-Connect007
Nolan Johnson talks with Shaun Dykes, a 50-year expert in the mining industry. Dykes gives a concise primer on mining development, and the amount of time and effort required to develop and supply the mineral resources we depend upon for the manufacture of printed circuit boards. There are many factors that play into when and where a mine is developed—and what can prevent a mine from ever producing minerals.
