Treatments of board circuit
Caring circuit in China produce many kinds of board circuit with different treatments and super quality at very good price for prototype and mass production.
Final PCB Surface Finish Comparisions will be very helpful to decide which one to use on your board circuit.
| Final Finish | Cost | RoHS | Fine Pitch Use | Flatness | High Speed | Rework Cycles | Shelf Life | Solder Joint | Solderability | Wire Bonding |
| Tin/Lead Solder (HASL) | Lowest | No | No | Bad | No | Few | 12 months | Excellent | Excellent | No |
| Lead Free Solder (HASL) | Lowest | Yes | No | Fair | No | Few | 12 months | Good | Good | No |
| OSP (Organic Solder Preservative) | Low | Yes | Yes | Excellent | No | None | 9-12 months | Good | Good | Yes |
| Immersion/White Tin | Low | Yes | No | Excellent | No | None | 9-12 months | Good | Good | No |
| Immersion Silver | Medium | Yes | Yes | Excellent | Yes | Many | 9-12 months | Good | Very Good | No |
| Immersion Gold (ENIG) Electroless Nickel Gold | Medium | Yes | Yes | Excellent | No | Few | 12 months | Good | Good | No |
| Hard/Deep Gold | High | Yes | No | Bad | No | None | 12 months | Bad | Good | No |
| Wirebondable/Soft Gold | Very High | Yes | Yes | Good | No | None | 12 months | Bad | Good | Yes |
