Solderability of a metal

Electronics Forum | Tue Mar 04 09:12:35 EST 2008 | davef

Q1. What would you recommend for the best practice or comparison? A1. We'd go with dip & look. It's easy and cheap, requires no advanced degrees in measurology. Have you reviewed "J-STD-002B - Solderability Tests for Component Leads, Terminations, Lu

Solder Shelf Life

Electronics Forum | Tue Mar 20 09:03:18 EST 2001 | moseschee

Hi, I'm looking for research/study done on solder shelf life by using accelerated aging process ( steam age or dry air oven bake at 150C & etc ) Perhaps you could help to advise correlation of all this acceleration test to actual solder shelf life

WHY CLEAN A NO-CLEAN FLUX

Technical Library | 2020-11-04 17:57:41.0

Residues present on circuit boards can cause leakage currents if not controlled and monitored. How "Clean is Clean" is neither easy nor cheap to determine. Most OEMs use analytical methods to assess the risk of harmful residues. The levels that can be associated with clean or dirty are typically determined based on the exposed environment where the part will be deployed. What is acceptably clean for one segment of the industry may be unacceptable for more demanding segments. As circuit assemblies increase in density, understanding cleanliness data becomes more challenging. The risk of premature failure or improper function is typically site specific. The problem is that most do not know how to measure or define cleanliness nor can they recognize process problems related to residues. A new site specific method has been designed to run performance qualifications on boards built with specific soldering materials, reflow settings and cleaning methods. High impedance measurements are performed on break off coupons designed with components geometries used to build the assembly. The test method provides a gauge of potential contamination sources coming from the assembly process that can contribute to electrochemical migration.

Effects of Thermal Aging on Copper Dissolution For SAC 405 Alloy

Technical Library | 2010-07-08 19:49:59.0

Aging characteristics of new lead free solder alloys are in question by many experts because of higher amount of tin’s effect on the diffusion of other metals, primarily copper, to create undesirable boundary intermetallics over long periods of time and even moderately elevated temperatures. A primary layer of intermetallics, Cu6Sn5 forms as the liquid solder makes contact with the solid copper substrate. This reaction however ceases as the solder temperature falls below that of liquidus. A secondary intermetallic Cu3Sn1, an undesirable weak and brittle layer, is thought to form over time and may be accelerated by even mildly elevated temperatures in electronic modules such as laptops under power. This project was designed to quantify the growth rate of Cu3Sn1 over an extended period of time in a thermal environment similar to a laptop in the power on mode.

. But too thick an intermetallic layer has an adversely effect because it is generally the most brittle part of the solder joint. Compared to lead-based solders, SnAgCu solders require a higher reflow temperature which leads to accelerated diffusion rates
