Wave soldering temperature

Electronics Forum | Thu Nov 04 11:56:33 EST 1999 | Tim Almy

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

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

I concur with your second approach. A profile needs to be tailored to the design of the board, the components, and the solder paste. Your first approach seems to try to balance lower quality soldering with a lower process complexity.

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

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

Temperature vs time is what soldering is all about. The faster you run your conveyor, the more heat will have to come from the pot for a given assembly. Example: You heat the board to 200F top side through the preheaters. Eutectic 63/37 melts at 361.

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder

Tim, I try to get 2-3 degrees C/sec (bottomside) rise on my boards through wavesolder. I like to get the topside to about 90-95 degrees C, but this is the optimum temp for the flux that I am using. To fast of a slope and you will burn your flux of

CAL's word of caution is right on. We tend to stay in the 220C-225C max. temp. on our profiles, and that's because the last heads up from engineering came on a part with a spec. of 230C max. temp. We just found out that one of our old SOIC's is spe

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
