Solderability
Commercial Coatings
1. No solderability guaranteed - Coating to thin (25 to 45
micro-inches)
Hot Air Leveled Coatings
Age Tests Simulate Extended Shelf Life:
a. Steam Age - Surface Oxidation -- 24-Hour Steam Age b. Dry Air Age - Diffusion of base material through coating, detrimental when diffusion reaches surface. -- 16-Hour Dry Air Age at 155 degrees Centigrade
Testing Used for Solderability:
1. Use non-activated flux, Type R 2. Solder pot (60/40 Tin/Lead) at 450 degrees Fahrenheit 3. Dip sample at rate of 1" per second for 5 seconds in pot 4. Look for 95% minimum coverage. 5. Testing available upon request.
