Our Solder Alloy Evaluation & Testing Service might be able to help and your business.
How do you ensure you make the right choice of alternative solder alloy?
If you have a good process with good yields and a reliable product, why would you need to change?
If you’re exempt from RoHS, you might not need to change.
However, maybe by changing you might:
It pays to get advice when choosing a new solder. Most companies talk with their solder suppliers or their subcontractors. If you’re looking for an independent opinion, supported by test-based evidence, then the experts at ITRI Innovation have the expertise and facilities to help you. For advice on the options available, call Dominic Lodge on 01727 871319.
You need to ensure suitability through representative testing. Thermal cycling is generally carried out, but it must represent the environment that your product is used in, but accelerated. After cycling, the product will need to be examined for evidence of damage to the joints using Optical microscopy & Cross-sectional analysis. You might carry out Mechanical testing, or Dye & Pry as well.
You will also need to think about the solderability and whether it will work with your present flux/components. A new alloy may require a different flux which could require Contamination testing.
