I am processing PCB's that have an n-tech osp coating and am finding huge inconsistencies in wetting. Some boards process clean with good wetting and the next has terrible wetting. The boards are stored and handled properly. Has anyone had this

I would be very interested in informations on OSP (organic solderability protection) on PCB�s. Good or bad experience with solderability, storage etc. There must be different types / brands of OSP. What type should be prefered ? And if possible

The solderability of the SAC305 alloy in contact with printed circuit boards (PCB) having different surface finishes was examined using the wetting balance method. The study was performed at a temperature of 260 _C on three types of PCBs covered with (1) hot air solder leveling (HASL LF), (2) electroless nickel immersion gold (ENIG), and (3) organic surface protectant (OSP), organic finish, all on Cu substrates and two types of fluxes (EF2202 and RF800). The results showed that the PCB substrate surface finish has a strong effect on the value of both the wetting time t0 and the contact angle h. The shortest wetting time was noted for the OSP finish (t0 = 0.6 s with EF2202 flux and t0 = 0.98 s with RF800 flux), while the ENIG finish showed the longest wetting time (t0 = 1.36 s with EF2202 flux and t0 = 1.55 s with RF800 flux). The h values calculated from the wetting balance tests were as follows: the lowest h of 45_ was formed on HASL LF (EF2202 flux), the highest h of 63_ was noted on the OSP finish, while on the ENIG finish, it was 58_ (EF2202 flux). After the solderability tests, the interface characterization of cross-sectional samples was performed by means of scanning electron microscopy coupled with energy dispersive spectroscopy.

. Most finishes will allow for this, with the main exception being organic solderability preservative (OSP). While this type of finish is eco-friendly, low-cost, and simple to manufacture and rework, it has virtually no shelf-life and can be easily damaged

? My second question is what kind of solder would you suggest for doing repair or adding a component to a surface mount board? Answer: The type of flux to be used is determined by the surfaces being soldered, such as HASL, OSP, ENIG, Gold, Pd, etc
