Here is a copy of a draft document on PIHR Inspection I have jotted down on a flight to Scotland yesterday, any comments suggestions etc ? I have already most of the photos for the standard but as you know there is nothing in the IPC document it just

On behalf of the SMTA International Technical Committee, we invite you to submit a 300 word abstract of your research for the 2016 SMTA International 2016 technical conference in Rosemont, Illinois. Papers should describe significant results from experiments, emphasize new techniques, and contain technical, economic or appropriate test data. We are looking for papers on a variety of topics related to electronics manufacturing including advanced packaging/components, assembly, business/supply chain, emerging technologies, harsh environment applications, PCB technology, and process control. Materials must be original, unpublished and non-commercial in nature.

Cleanliness is a product of design, including component density, standoff height and the cleaning equipment’s ability to deliver the cleaning agent to the source of residue. The presence of manufacturing process soil, such as flux residue, incompletely activated flux, incompletely cured solder masks, debris from handling and processing fixtures, and incomplete removal of cleaning fluids can hinder the functional lifetime of the product. Contaminates trapped under a component are more problematic to failure. Advanced test methods are needed to obtain "objective evidence" for removing flux residues under leadless components.Cleaning process performance is a function of cleaning capacity and defined cleanliness. Cleaning performance can be influenced by the PCB design, cleaning material, cleaning machine, reflow conditions and a wide range of process parameters.This research project is designed to study visual flux residues trapped under the bottom termination of leadless components. This paper will research a non-destructive visual method that can be used to study the cleanability of solder pastes, cleaning material effectiveness for the soil, cleaning machine effectiveness and process parameters needed to render a clean part.

Over the last few years, there has been an increase in the rate of Head-in-Pillow component soldering defects which interrupts the merger of the BGA/CSP component solder spheres with the molten solder paste during reflow. The issue has occurred across a broad segment of industries including consumer, telecom and military. There are many reasons for this issue such as warpage issues of the component or board, ball co-planarity issues for BGA/CSP components and non-wetting of the component based on contamination or excessive oxidation of the component coating. The issue has been found to occur not only on lead-free soldered assemblies where the increased soldering temperatures may give rise to increase component/board warpage but also on tin-lead soldered assemblies.
