Gawd. Sure FR-4 will meet those conditions. Tg [check the fine SMTnet Archives for discussion on Tg] of FR-4 is 130�F or so. Consider: * Is the delT between Tg and the upper operating [or storage] temperature acceptable for your application? * D

Is 260 degrees C / 500 degrees F the optimum temperature for wave soldering ?

If you will place a temperature strip on the board during wave soldering process you will get a max of 210 F or 98.8 C which is normal on the standard wave temperature. The problem on the 10% solder on the TH via hole can be caused by insufficient fl

Looking for anyone who has experience with high temperature soldering. Need to determine why solder joints are failing. Thermocycling of unit is -40C to +140C, 30 minute dwell time, 10 sec. transition time Your help is appreciated Ed Holton Hella E

Per our staff here at ACI......... Higher Temperatures maybe necessary to achieve good solder process results. The alloy formed when HASL coating protects the copper is the same as that when OSP provide protection. Temperatures may be increased to im

I'm with John. Back in the old MIL-2000 days, the pot temperature was 245-275C (475-525F). Now, 240-260C (460-480 F) is more accepted for eutechic (eutechicish) solder. My2� Dave F

Hi Tim It sort of depends on the solder alloy being used and the particular assemblies being soldered. If you are using the usual 63/37 alloy I would consider 500 to be a bit warm unless the assembly required it. Some alloys would require a higher

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu
