I'm curious what you use for PCB Support. Are you using a dedicated support plate or are you using magnetic pins or some type of Grid-Lock system?

Support bars, so essentially the board is sitting ontop of beams that make a table. Fully supported with no soft spots

I almost always go with an overprint as long as it's feasible. I haven't had much problem with solder-balling when overprinting. I'd give it a try and see how it works for you.

Solder balls floating around on the air currents of a reflow oven. I sincerely doubt it. Could the solder on your gold fingers be from: * Excess placement force during P&P? * Ejactula from solder deposits during rapid preheat ramp rates? * Ejactula

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

The issue is surface tension around the connector. Your tip needs to have more surface tension than the pins of the connector as it forms a cluster when being soldered. When I used to solder superfine connectors with a metcal iron it had a horses hoa

Hi Im looking for a person who have a experience with Intel® Core™ i3-5157U (i5) Processor soldering (CL8064701478404). I want to compare our experience because i'm not sure about aur spare parts and our soldering way. They are original or not, becau

Are you worried the terminations might b oxidized? Do a dip test. If you have a solder pot carefully dip one termination of the cap into the solder. And see how well it wets. If that test doesn't satify the powers that be, then you can design a more

Use a standard that everyone will recognize. If you say, "The solderability test was performed in accordance with ANSI/J-STD-002 'Solderabiility Tests for Component Leads, Terminations, Lugs, Terminals and Wires'” [ipc.org/TOC/J-STD-002C.pdf ], every

Peculiar that ENIG boards are corroded, not that it can't happen. * J-STD-002, Solderability Tests for Component Leads, Terminations, Lugs, Terminals and Wires * J-STD-003, Solderability Tests for Printed Boards The first person I'd talk with is my
