While some customers are investigating frontiers in MEMS (Microelectromechanical systems), others are delving into the inherent superconductive properties at milliKelvin temperatures, while still others are exploiting the radiation response characteristics of aluminum. For the R&D personnel at Omni Circuit Boards, the requests have presented some interesting challenges.

Given that we are leaders in **Immersion White Tin PCB fabrication** here at Omni, it goes without saying that we are heavily in favor of its use. To understand why, you first have to understand the reason behind our preference for white tin in the first place. Traditionally, printed circuit boards have been finished with a coating of material to protect them from oxidation and allow for components to be soldered onto them in a reliable consistent way, this is usually specified to as "PCB Finish" and requires the use of Lead (HASL) and vast amounts of water during processing (All  other PCB finish types).  Mon, Mar 11, 2019 @ 03:32 PM [Omni Team](https://www.omnicircuitboards.com/blog/author/omni-team) [Printed Circuit Board Manufacturing](https://www.omnicircuitboards.com/blog/topic/printed-circuit-board-manufacturing) [Read More »](https://www.omnicircuitboards.com/blog/bid/261735/what-you-should-know-about-immersion-white-tin-pcb-manufacturing) ## [Understanding Printed Circuit Board Manufacturing: Electrical Testing](https://www.omnicircuitboards.com/blog/bid/293110/understanding-pcb-manufacturing-electrical-testing) [![](https://www.omnicircuitboards.com/hubfs/Mania%20Legacy%20E-Tester%20Machine%20Speedy%20MPP4504.jpg)](https://www.omnicircuitboards.com/blog/bid/293110/understanding-pcb-manufacturing-electrical-testing) ## PCB manufacturing facilities routinely perform Electrical Testing with “Flying Probe” testers which are well suited to smaller production runs. **For short runs, the flexibility of quick set-up ensures cost effective Flying Probe tests outperform the lead-time, cost and fixed designs of dedicated test beds.** With Flying Probe tests, no fixtures need to be prepared, only data files. Flying Probe tests are able to reveal not only shorts and opens produced by the manufacturing process but have also been known to expose design errors.

They may not feel comfortable down mouthing the competition in public but a process? Well that’s fair game. What the salespeople don’t know or won’t tell you is the Immersion Tin used as a finish for circuit boards completely dissolves in the solder used in the circuit board assembly process.

If layer to layer registration, tolerances for hole size, location, film expansion and registration have not been taken into account then manufacturing will experience high reject rates and increased costs.
