Hi Can anyone tell what is a Ramp to Spike Profile? Rgds

Ramp-to-Spike profiles can be used with most Sn/Pb alloys as well as the SACs.

From the temps you list, I'm going to assume you are using leaded solder. What type of oven profile are you using: Ramp-Spike or Ramp-Soak-Spike? I think you will have better results if you use the Ramp-Soak-Spike type of oven profile. Better chan

After looking at your profile, some general thoughts.... Your profile looks like what is commonly called a ramp-spike profile and not a ramp-soak-spike profile. Going off of Sarason's comment, you may not have a good soak period before the spike in

We have an ERSA machine here where we have solder "spikes" occasionally. We have made sure our flux is dispensing properly, we have adjusted z axis speeds, our preheater is heating properly, adjusted XY speeds, etc. Can anyone think of something we m

Hi Russ I happen to come across a article about reflow profile. Other than Ramp-to-spike(RTS) & Ramp-soak-spike(RSS), its introduce a new reflow profile & call it LSP. Is it possible to give me your email address & I will send the article to you?

we are using solder paste WS609 and OM5100.Relow oven: forced convection type. For WS609 and OM5100, straight ramp up profile is suitable for low to medium thermal mass assemblies and preheating may be required for high thermal mass assemblies. How

you using a ramp soak spike or ramp to spike profile? you may be burning out your flux in preheat if you ramp to fast or for too long, most pastes have 2 activation points for their flux one at low temp and one at higher temp. Try a ramp to peak pr

Okay, there's a debate here at my company. We build a card here that, often times, we get batches where there is excess HASL in the VIA hole barrels. Here is the problem that this causes: During the "1st reflow", the excess HASL bleeds out of the
