We do one of two things here; 1. We have cut up a bar of solder to different lengths, wieghts, etc. and place them on top of the offendinding floater, or 2. On selective wave pallets we will build a jig/clamp to hold down the part.

this is a two row connector that I'm talking about. We were going to select solder it or wave it but we are just trying to make the process faster and if I can get this to work, it will definitely save time for us.

| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

Before anyone tells me to search the fine archives, I already did! I typed Sn100c and Reflow, and nothing came up. Anyway, any of your folks out there run Sn100C across the board - Reflow, Wave and/or Selective, and Hand-Soldering? If so, please p

There are many users of SN100C in reflow. SN100C was originally introduced as a wave solder alloy which offered cost savings over SAC, no solder pot erosion, and high fluidity. Since it is eutectic, no plastic range, the joints have a smooth, shiny

Hello All, We have a small selective solder machine from RPS, a Rhythm SS, purchased used with SN100C in pot. For a couple of years we have used this machine and gotten good results. We have been adding SN995 to the pot as it needed more solder. Then

I mean...there are a ton of possibilities for bridging on selective solder before you ever get to alloy purity. Are the bridges happening consistently in the same spot? Are the leads too long? Can you modify the approach/exit/peel off to address? Wh

Just a thought.... Some Fluxes require temperatures upto 260F (127C). Are you using water based flux or solvent (alcohol). I have noticed that many wave machines are NOT capable of preheating adequately when using water based materials. This can

We used to use those, back in the bad old times. basically, it's a router with a blade on it that is used to trim the leads of PTH components that are mounted on boards. Nasty process. Difficult to control. Messy, firing cut leads all over the plac
