Hi Solderdoctor! Days been great especially as it's nearly over. Don't see many of those machines over here anymore due to healthy competition from local supplier. Only been in industry myself nineteen years so spring chicken I suppose. Mind you sold

1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? 2. What is the �Low- Temperature Phase� in any solder paste alloy? 3.W

We put it in one flow soldering machine probably 12 years ago now worked really well but was extremely brittle you maybe better off with the 1% Ag alloy as its more ductile. Look at AIM Solders site if you want further information on the alloy Itis a

Agreed. In my experience you will not wet solder to: Platinum Iron Constantine Tungsten Carbide titanium Chromalloy allomega alloy 303, 304 ...and the list goes on and on. You will either need to weld or braze. These are high temperature prcesses

Pb free vapor soldering

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

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 Hannu, You just gave a very realistic and practical view of the lead-free dilemma. The main reason that your coil coating doesn't get removed is because of the inability of lead free alloys to wet the surface and conduct the heat. Higher temperat

Just a thought.... Some Fluxes require temperatures upto 260F (127C). Are you using water based flux or solvent (alcohol). I have noticed that many wave machines are NOT capable of preheating adequately when using water based materials. This can

Good Lead-Free soldering Iron???

I am partial to Weller for the small rework irons. I use both the WSL with WMP (current model) and some older EC1302 irons with their power supply (I forget the model, but the one with analog setting knob and digital temp readout). I actually prefe

reflow / soldering temperature

Electronics Forum | Thu Apr 05 08:36:35 EDT 2001 | jmlasserre

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
