HELLO NANCY,
THE THICKNESS RANGE OF MOST OSP FORMULATIONS ARE IN THE RANGE OF.12-.35
MICRONS. THIS THICKNESS RANGE GENERALLY PROVIDES SUFFUCIENT PROTECTION.
PLEASE NOTE , HOWEVER, THAT THE THINNER THE OSP DOES NOT NECESSARILY
MEAN THE LEAST IN SOLDERABILITY PROTECTION.
AS FAR AS TESTING THE THICKNESS, I AM MOST FAMILIAR WITH AN ORGANIC
ACID DISSOLUTION TEST WHERE YOU DISSOLVE THE COATING OF OFF A COUPON A
COLLECT THE FLUID. THEN, A UV-VIS METHOD IS EMPLOYED AGAINST A STANDARD
AND THE THICKNESS IS DETERMINED FROM THAT.
LET ME KNOW IF YOU NEED FURTHER INFOMATION.
