PCB Process

Immersion Tin PCB Board

The Immersion Tin surface treatment on the PCB boards has a very thin layer of tin, applied over the copper layer on the electronic PCB. This method is a Lead-Free PCB alternative but has a consistently flat surface, which solders well but the cost is relatively higher than HASL Lead Free. This tin surface finish can protect the copper under the tin layer from oxidation for 1 year according to IPC standard.

The Immersion Tin surface finish has a relatively long shelf life compared to other surface treatment , but does require careful handling during the PCB Assembly Process. Copper and tin however have a strong affinity for one another. The diffusion of one metal into the other will occur inevitably, directly impacting the shelf life of the deposit and the performance of the finish. The negative effects of tin whiskers growth are well described in industry related literature and topics of several published papers.

If you have any more questions regarding the immersion Tin PCB boards, contact us today, our sales team and engineering team will be very pleased to answer your questions, look forward to seeing you soon.
