MATERIAL FOR SOLDERING MASK

COMPOSTITION:

CONTAVAL M AM is a laminate consisting of glass-mat, epoxy-resin with conductive additives and teflon. The material can withstand 300°C. CONTAVAL 2576 GP is a laminate consisting of E-glass cloth, conductive additives and epoxy-resin. The material can withstand 280°C.

APPLICATION:

CONTAVAL M AM and CONTAVAL 2576 GP are used as soldering bath carriers for printed circuits, when sensitive components ask for ESD working conditions. CONTAVAL 2576 GP has better mechanical properties than CONTAVAL M AM, because it is made from E-glass cloth and not from glass-mat, however, in general it can withstand fewer cycles. CONTAVAL M AM also consist of teflon and therefore it is use for the most demanding soldering processes. CONTAVAL M AM on average can handle between 8.000 – 20.000 cycles (1) The number of cycles on CONTAVAL M AM can be extended if the surface is ground down by app. 0,50 – 1,00 mm. Grinding should be done using tools with a larger diameter and at a slower speed. This can cause the temperature to increase and the teflon in the material to melt, which can result in a kind of glazing (facing) on the material. With this facing, the life time of CONTAVAL M AM, can be further extended by 20 – 30 %. CONTAVAL 2576 GP on average can handle between 7.000 – 15.000 cycles Application in practice has shown that the life of a solder mask depends on various factors, from the diseing of the solder mask, fluxes, cycles of use, etc. Therefore the actual number of cycles could be different from those mentioned above.

PROPRETIES (BOTH MATERIALS):

CONTAVAL is antistatic, is suitable for using lead-free technology and it is suitable for exposure to red light. CONTAVAL has excellent mechanical properties even at high temperatures and shows conductivity parallel and perpendicular to the layers necessary for ESD applications. The special epoxy resin used as well as the smooth unsanded surface result in high chemical and temperature resistance. CONTAVAL can be easily cut and machined with diamond tipped tools and high speed machinery.

AVAILABILITY:

TYPE	THICKNESS in mm	DIMENSIONS in mm
CONTAVAL M AM	3,00 – 16,00	1200 x 950 ± 20
CONTAVAL 2576 GP	2,00 – 30,00	1240 x 2800 ± 30
