Hello Ok there is not much info here. What you have to mae sure of is several key factors. 1. Have you entered the correct stencil thickness. 2. Are you using the stencil gerber (not the paste layer) The paste layer is usually not adjusted for ap

I'm new to SMT. Now, i'm making program for SPI machine to inscpect for solder paste of SP60-MU. I think this is a very good printer but some times, my program shows only 50-60% of volume transfer; and the average height is very high: nearly 200 pct.

Is that accurate? If so, what are your aspect & area ratios? [Similar to the JerryS comment above.] * You say, � � and the average height is very high: nearly 200 pct.� => Our troop can make paste that height too. They snap the stencil-off a fast as

What is the viscosity of your lead free paste vs. your lead paste?

Hi all, Recently I had problem with printing the lead free solder paste, almost every board has bridging especially on the fine pitch locations. Anyway this problem never happens when we use leaded solder paste. So I would like to ask if there are a

Are you saying that increasing the frequency of cleaning to every 3 boards *reduced* bridging, or that it's just something you tried? I don't understand why that would help(in my experience it has reduced "insufficient solder" conditions but not brid

We previously labelled PCBs after assembly but before AOI. Now we need to trace panels during assembly as well, so have the need to apply labels before the assembly process starts. Our stencils are thus not stepped to accommodate labels. I suppose t

Mark, We print and dispense with Amicon "D 125 F". Solvent used is Electrolube "SSS", which is also used for solder paste removal/pcb cleaning for misprints and rework both manually and ultrasonically. I like it - good stuff but at $25 AU per litre i
