Head in Pillow X-ray Inspection at Flextronics

Manufacturing technology faces challenges with new packages/process when confronting the need for high yields. Identifying product defects associated with the manufacturing process is a critical part of electronics manufacturing. In this project, we focus on how to use AXI to identify BGA Head-in-Pillow (HIP), which is challenging for AXI testing. Our goal is to help us understand the capabilities of current AXI machines.

A PROCEDURE TO DETERMINE HEAD-IN-PILLOW DEFECT AND ANALYSIS OF CONTRIBUTING FACTORS

Head-in-Pillow (HIP) defects are a growing concern in the electronics industry. These defects are usually believed to be the result of several factors, individually or in combination. Some of the major contributing factors include: surface quality of the BGA spheres, activity of the paste flux, improper placement / misalignment of the components, a non-optimal reflow profile, and warpage of the components. To understand the role of each of these factors in producing head-in-pillow defects and to find ways to mitigate them, we have developed two in-house tests.

Advanced Second Level Assembly Analysis Techniques - Troubleshooting Head-In-Pillow, Opens, and Shorts with Dual Full-Field 3D Surface Warpage Data Sets/

SMT assembly planning and failure analysis of surface mount assembly defects often include component warpage evaluation. Coplanarity values of Integrated Circuit packages have traditionally been used to establish pass/fail limits. As surface mount components become smaller, with denser interconnect arrays, and processes such package-on-package assembly become prevalent, advanced methods using dual surface full-field data become critical for effective Assembly Planning, Quality Assurance, and Failure Analysis. A more complete approach than just measuring the coplanarity of the package is needed. Analyzing the gap between two surfaces that are constantly changing during the reflow thermal cycle is required, to effectively address the challenges of modern SMT assembly.

Hidden Head-In-Pillow soldering failures

One of the upcoming reliability issues which is related to the lead-free solder introduction, are the headin-pillow solderability problems, mainly for BGA packages. These problems are due to excessive package warpage at reflow temperature. Both convex and concave warpage at reflow temperature can lead to the head-in-pillow problem where the solder paste and solder ball are in mechanical contact but not forming one uniform joint. With the thermo-Moire profile measurements, this paper explains for two flex BGA packages the head-in-pillow. Both local and global height differences higher than 100 um have been measured at solder reflow temperature. This can be sufficient to have no contact between the molten solder ball and solder paste. Finally, the impact of package drying is measured

Head-On-Pillow Defect - A Pain in the Neck or Head-On-Pillow BGA Solder Defect

The head on pillow defect is becoming more common. This paper describes one such occurrence for an OEM and explains how it was dealt with. In this particular case it was solved by application of problem solving skills by the OEM, component supplier and the solder paste provider

Melfs drops down from nozzle -- I've some special nozzles for melf packaged diodes. When I am trying to mount it on pcb, nozzle picks up the diode and place it well. After 5-6 times of placing, diodes keep drops down to it's package from nozzle. It's like the vacuum doesn't enough for it or vacuum turns off while picking. Nozzle takes the diodes up for about 3mm & 0.12inches and then it drops down. It repeats everytime i start the proggram. It's working good then it doesn't pick up after a while.

Using AMRs in Production -- I'm curious who may be currently using Automated Mobile Robots (AMRs) or Automated Guided Vehicles (AGVs) in production. I've seen a few companies using them to transport SMT parts from the warehouse to the SMT Line. I'm wondering what others are doing. Anyone care to share? Thanks!
