Make sure you are providing an adequate moisture bake out prior to wave soldering. It sounds moisture related since is so random. I would suggest perhaps 120C for a minimum of 8 hours to drive the moisture out, and then complete your wave soldering

Hi - I am trying to set up a visual display of the component attrition rate from our Siemens P&P Machines. There is OIS SW running on each machine so we can query a certain amount locally at each machine. Is there a way of having a more userfriendly

Hi, Solution of the ASM / Siemens is nice but in terms of the display of the results is quite limited and sometimes difficult to define. Our clients built (some of them with our help) separate software takes the data from the machine (the database)

To most of our boards I give 20-30% tolerance in both directions. From experience if you have big aperture on your stencil, the squeegee will scoop certain amount of paste from this aperture and you will see lower height. Depending on your board supp

m_imtiaz, Over the last 15 years or so I've found that using the stencil foil thickness +2mils/-0mils has worked very well. For example, if you have a 5mil stencil thickness your upper control limit would be 7mils and your lower control limit would

Hi guys, can somebody explain me why and how immersion gold is better than hard gold platting or vice versa? We are not going to do any welding operation over the Gold platted area, rather we just move a sliding contact over the gold pl

Hello! I have a problem with one of the products here, we use a pallet to run the board on the solder wave, when the board gets solder and you inspect the board you notice that for some reason the first pcbs that touches the wave are ok, even a litt

One thing you could check/monitor is the temperature in the pot/wave. As boards run across the wave, they will cause fluctuations in the wave temperature. The heaters should hep with minimizing this; but, if you're running a lot of boards in quick

A little confusion here. Are you running several boards in one pallet and the last boards are looking poor or is the issue getting worse as the day progresses (like as the pallets get warm)? - If it is the last boards in the pallet, then you may wan

we do that and there's a variation on the solder temp. sometimes around 10 degrees, we have 2 solder pallets that are run in intervals of roughly 3 1/2 minutes a part (the time that take the operator to put all 3 terminals in a 42 pcbs per board, and
