Comparing Soldering Results of ENIG and EPIG Post-steam Exposure
Electroless nickel immersion gold (ENIG) is now a well-regarded finish used to enhance and preserve the solderability of copper circuits. Electroless palladium immersion gold (EPIG), meanwhile, is a new surface finish also for enhancing and preserving solderability—but with the advantage of eliminating electroless nickel from the deposit layer. This feature has become increasingly important with the increasing use of high-frequency PCB designs whereby nickel’s magnetic properties are detrimental.
Selecting the Proper Flex Coverlayer Material
Coverlayers are polymer materials used to cover and protect the copper traces of the flex circuit product. There are a number of different options available for protecting the circuits, and they serve different design requirements in terms of cost, performance, and flexural endurance optimization. When specifying the choice, it is critical to call out not just the type of coverlayer material but also the thickness requirement. This can be very important in certain types of constructions, especially when a flex circuit will experience dynamic flexing during use.

Seven Key Steps to Selecting a New EMS Partner
Choosing to outsource your electronics manufacturing to an EMS provider requires careful planning and consideration. And even once you’ve made your decision, there may still be things that test you or that don’t go quite to plan. An experienced EMS partner has been there before; they understand the challenges, and they’ll be able to support you through the process to ensure you achieve your goals.
Conformal Coating Selection: Conventional vs. Two-part
As assemblies become more densely populated, and housing/casing designs become more permeable to save weight, the use of conformal coatings is essential to protect the assembly from its operating environment and ensure acceptable reliability for the application intended, especially when operating in hostile environments.
Which Matters Most: Unit Cost or Total Cost of Supply?
The primary objective for any OEM is to design, manufacture, and deliver high-quality products in the most cost-effective way possible. When demand patterns change, or there is an increase in competition, it can be easy to rely on the calculation of unit cost to relieve the price pressure. But, as many manufacturers are discovering, choosing to base their outsourcing decisions purely on unit cost may not always reap the expected benefits in the long term.
