Table of Contents
Dynaloy Dcap
Advantages:
- Acid free decap (gentle on metals?)
- Datasheet claims it flakes, not swells. If so this makes it superior to swell epoxy removers which can damage bond wires
- Does not eat aluminum (or one should hope anyway since they say its fine to heat in an aluminum container…)
Disadvantages
- Expensive compared to simple acids (Ellsworth sells it from about $184-131 / quart)
- Must be used hot (150C)
Instructions for IC package [Dynaloy decap data sheet]
Do:
- Pour into glass, stainless or aluminum beaker
- Heat to 150C. Do not heat further. Boils at 189C, flash point at 95C
- Use metal tongs to remove sample
- Wash sample with water, IPA, or MEK to remove Decap
Notes:
- To reuse: filter it
- Store above 70F as will crystalize below 60F. If so just re-heat
- Tarnishes silver and tinned leads
- Use rubber or polyethylene gloves
