thanks for the feedback....but what's your delta T and how will you know that you are within the delta T range ?...I think this is the main point of the above topic...can you elaborate more on how did your company get Delta T ? thanks and regards,

Here's what I believe is happening. The main difference between the HASL boards and the gold plated boards is that HASL boards are pre-soldered. HASL boards need very little flux activity to get good hole fill and the machine settings have a wide pro

Our new Soltec Delta 3 has this feature (they call it mainwave pushup) where you can add up to 60 rpm to the pump after the leading edge passes over the wave. Unfortunately, our old Delta Wave doesn't have this feature. Ideally we'd like to set it

Good point about the cycle time, we've had a think about this issue, we are set up mainly to do small batch sizes, the reasoning for thinking about laser soldering is that there is no requirements for wave solder tooling, on a batch of 50 boards or s

Mike, we use carrier's as a matter of course on all wave products, it let's us keep the conveyor width the same all the time so speed's up change overs and eleimiates one more thing that can be set wrong. The main aim of the exercise is to be able

We aquired an ERSA ECOSELECT 2 selective soldering machine. So we are going through a learning curve and I would like to hear from ERSA users on this subject. The main concern is to keep the miniwave steady, it seems that it " bounces" a lot and is

Are you using a water based flux? Are the solder balls mainly around or near non-plated holes or near the edges of the PCB? If so the preheat must be set so the water content of the flux is fully evaporated before the board hits the solder wave. If

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a

John, We regularly wave solder electroless silver finished boards (Alpha Level)with mixed SMD and through hole parts and do not have any problems. We have changed a number on PCB's from HASL to electroless silver, mainly for the benefits at SMD whe

Well my process is I'm running my belt speed at 3.50fpm and about 215 to 225 degrees top side. I got my main wave down to a little less than half the board thickness. I'm not using a hot air knife cause we thought it might create more of a problem th
