Are boards produced using Vapor phase ovens dirtier than N2 Reflow oven. Are there any studies/papers someone can point to? if not what are the methods to verify this? is IPC specified SIR test using 24B SIR test coupons? please advise. thanks in adv

We know SIR coupons are not ROSE coupons, but coupon boards are: * IPC-B-24 (copper and HASL, FR-4 and polyimide) * IPC-B-36 (bare copper and HASL, FR-4 and polyimide) * IPC Phoenix board (bare copper, FR-4) * IPC-B-25A (FR-4, bare copper only)

Many electronics manufacturers perform SIR testing to evaluate solder materials and sometimes the results they obtain differ significantly from those stated by the solder material provider. The difference in the results is typically the result of SIR coupon preparation. This paper will discuss the issue of SIR coupon preparation, board cleaning techniques, and how board cleanliness directly affects SIR results.

Conformal Coatings are often used to increase the reliability of electronic assemblies operating in harsh or corrosive environments where the product would otherwise fail prematurely. Conformal coatings are often qualified to international standards, intended to enable users to better differentiate between suitable conformal coating chemistries, but always on a flat test coupon, which is not representative of real world use conditions. In order to better correlate international standards with real world-use conditions, three-dimensional Surface Insulation Resistance (SIR) test boards have been manufactured with dummy components representative of those commonly used on printed circuit assemblies...
