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)

IC package procedure [Dynaloy decap data sheet]:

1. Pour into glass, stainless or aluminum beaker
2. Heat to 150C. Do not heat further. Boils at 189C, flash point at 95C
3. Use metal tongs to remove sample
4. 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
