Presentation Abstract
Electrical reliability is a fundamental requirement for every circuit assembly. Surface insulation resistance is a globally accepted standard for predicting the electrical reliability of a printed circuit. This paper will attempt to measure how the reflow profile used in an SMT process affects the electrical reliability of three no-clean solder paste residues.
Three different reflow temperature vs. time profiles, a 1.5 °C/s ramp to 230°C, a 1.5 °C/s ramp to 250°C and a 90 s soak at 175°C with a 230°C peak, were used to reflow three lead-free solder pastes in both air and nitrogen atmospheres. Fourier transform infrared spectra of the reflowed flux residues shows how reflow profile conditions and atmosphere affects the decrease of a peak around 1700 cm-1 and the appearance and increase of another peak at 1600 cm-1. The 1700 cm-1 is smaller for flux residues that were reflowed under hotter conditions and for those that were reflowed in air. The peak at 1600 cm-1 is larger for residues exposed to hotter reflow profiles in air, but is hardly present for residues reflowed in nitrogen. The affect of these reflow conditions on surface insulation resistance (SIR) per IPC-TM-650 Method 2.6.3.7 at 40°C 90% RH and 12V bias has been studied. This measurement shows that hotter reflow conditions result in higher SIR values for two of the pastes, as would be expected, but has a smaller affect on the third paste.

Presentation Abstract

Is it the irate customer? Is it the flux residue? Is it the friendly SCAQMD or OSHA inspector? You’ll laugh; you’ll cringe! You’ll have fun! Forget the success stories. We all tend to hear glowing reports of successes. Research has shown that successes are reported; failures are not. You can learn more from failures than successes. Hear about real-life cleaning mishaps. Hear about “partial successes.” Learn how to interpret success stories and adapt the approach for your own manufacturing facility. Come away with great ideas to clean electronics assemblies and to avoid costly investments in process equipment and chemicals that are not right for you. Understand how to fix small issues before the line goes down, before you lose business. Unlike reality T.V, most names will be changed to protect the innocent.


Technical Session 3
2pm to 2:30pm
Effects of Shelf Life and Manufacturing Environment on Solder Paste

Speakers

Neil Poole

Henkel


Speaker Bio
Dr.Neil Poole is a Senior Applications Chemist in Henkel Technologies, electronics assembly materials application engineering group. He is responsible for all of Henkel's assembly products including soldering products , underfills, PCB protection materials, and thermally conductive adhesives. He holds a Ph.D. Catalysis and a B.Sc in Chemistry from the University of Edinburgh in Scotland.

Presentation Abstract
A number of studies have shown that up to 60-80% of all electronics assembly defects are related to the solder paste printing and reflow characteristics. Since the introduction of lead free solder paste, manufactures have concentrated on improving the printing performance and widening the reflow window, but the number one problem in assembly of circuit boards still point to the solder paste. While some of these defects can be blamed on environmental elements, temperature, and humidity on the factory floor or possible temperature variations during the shipping and handling. The condition of the paste, while fresh is usually good, but many of the process defects may be attributed to the logistics of getting material from the vendors to the shop floor. In this presentation Henkel will explore effects of shelf life and manufacturing environment on solder paste.
