Hi, we are about to change solder paste for cost issue. Currently using a no clean Sn63 solder paste and tried several others, all no clean, Sn63 and Sn62. Want to ask about reliability test: we did thermal shock test for 8 days. The flux residue cha

I have read an interesting article on pip plus, where they say "However, both PIP processing and the use of solder preforms are well-proven methods. The combination of pin-in-paste plus solder preforms delivers numerous benefits compared to a combi

I received data sheets from a paste distributor in which Amtech gives a recipe how you can mix solder cream. They deliver the flux in plastic jars and the solderpowder in foil packages. You must mix the two components with a simple mixing tool. Has a

Omid, In some cases we have been able to restore acceptable solderability by dipping the leads (one side at a time) in an active flux and then re-tinning. Usually a good visual inspection after tinning would reveal whether this was going to work.
