| Is feasible to have an electronic manufacturing company near the beach? How affect the corrosion the electronic components? | I guess it depends what you mean by 'near'. Will the building be a custom design or an existing one? What kind of product

| While inspecting incoming PCBs we detected around all plated-through-holes (only there and all in the same place) some halfmoonshaped light rings that match obviously only with the pink ring symptom shown in the IPC-A-600 chapter 2.5.2.. That would

| | We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have t

Based on work I have been doing recently the most common reasons for component loss is board flexture and vibration on the reflow process. If parts do not reflow then weight is not an issue. There is a video on double sided reflow and PIHR from the S
