| The implementation of internal continuous preheat during selective soldering improves thermal distribution and solderability of difficult assemblies. |
| Achieving this desired surface roughness delivers the expected performance criteria such as solderability, wire bondability and corrosion resistance. |
| Where we get into trouble is when we stop using the surface finish as a solderability preservative and leave the metal areas unsoldered. |
| This material is commonly known as terne and is used where ease of solderability and a degree of corrosion resistance are desirable. |
| The data show poor solderability when coupons were reflowed in air. |
