Since side fillets are not a requirement for QFNs/BTCs due to some packages not having wettable side terminations, how does one determine if the side terminations are actually solderable/designed for wetting? Is it simply if the side terminations

| | What does the term "poor wetting" mean as a defect code ? "Poor" should mean unacceptable when surface (component or PCB solder termination areas) wetting does not provide acceptable solder joints. Unacceptable wetting of PCB solder termination

Unlike components where the solder paste has been reflow soldered, wave soldered components have an "infinite" amount of solder available to make a solder connection. If you have good solder flow, pad and component termination size are going to be b

Hello thanks for the quick response actually both terminals are for a receptacle, both terminals has to have that solder bridge.

we manufacture a range of ceramic parts that have silver termination,there is already a small leaching problem (absorption of the termination by the solder in liquid form)with Sn62 that we live with, having to implement unleaded solder they are norma

Sal: JAX makes good points, but I�d like to think about this differently. It sounds like the poorly soldered connection is lifting the whole connector, so that termination floats on top of the solder, rather than submit to the wetting force and be

Hi Slaine, The terminations are still present on the component but all the solder (including the pad finish) has coalesced on to the terminations. The termination that normally is shiny and bright in colour has turned matte grey on that zone where t
