RoHS compliant boards are produced using laminate materials of varying decomposition temperatures with a number of different final finishes. We can provide you with a lead-free solder finish using SN100CL ?a lead free alloy of 99.3% tin/ 0.6% copper with a trace of nickel. It is an alternative to more expensive finishes and makes a flatter pad than its leaded counterpart.
We can also finish plate your boards with either electro-plated or immersion gold. We just recently added Electro-less Nickel Immersion Gold (ENIG) and Immersion Silver to our production floor. And of course we offer a standard "hard" electro-plated gold finish over electro-plated nickel.
The laminate materials that we are processing RoHS products on are capable of withstanding temperatures between 260?and 288?C for 20 seconds or more depending on the laminate selected.
