I am interested in RoHS "through-hole soldering": We have a problem with solder wetting and fillet during selective and wave soldering, with a Ni/Au PCBA!! Different fluxes has been tested, but this is really a big issue. Now; there is only a few fl

Not as such. Choices are: 1 Cut and epoxy some board foil from your board fabricator. 2 Sacrifice part a pad repair kits from the likes of: * Engineering Lab 905-785-1982 * Circuit Technology Center 978-374-5000 * General assembly suppliers catalog

Yes, there have been many issues with the fast dissolution of copper by the SAC305 alloy. In fact, there are companies who have disqualified it for repair operations due to loss/thinning of the pads. SN100C dissolves copper much slower than SAC305 an

Based on what you have said so far it would be worth trying extra pads and as you may know the drainage pads should be a minimum of three times the length of the pads before them to be effective. Also take some parts stick them to a glass plate and r
