Hello
When I have a component lead poking through a hole on a pcb, I first tin my iron and clean it well, I heat the joint the opposite side to where I then feed my solder. I take the iron away and often there is a shiny joint.
However if I thin a wire and melt some solder on a board track then reheat and put the tinned wire in the heated solder, i find when i remove it and keep it still the joint still turns dull and grey coloured even after applying heat for a long time.
Is this a cold and bad joint or is this ok
Thank you for any replies
