We have an inline MPM 25 HiE with 2D inspection. We are needing to put in a 2nd line. We have ordered another identical used stencil printer but are wondering if we should upgrade to a newer machine with 3D inspection, automated paste, etc. Will

You can save your boms and Partminer will let you search that data along with capturing what you paid last time the time before and maybe if there are any opportunities to get the part cheaper somewhere else. Helps us keep track of the parts we have

Did you try pre-tinning your board on this suspect pad/s to see if it improved wetting/solderability prior to printing/SMT placement and reflow? Does the pad/s not soldering tie to a ground layer? I would connect a T/C to each pad of the same part an

that crossed our minds - overloading of the oven but in reality we produce 5 references with very little output difference (close to 2 sec difference) so it should be a problem since a few yeats and on all references...? no only on 2 references from

What is the common practice for cleaning Tin/Lead and Lead Free solderpaste on stencils- some machines have filtration I'm told, so its not an issue according to the mfrs. On machines that don't have filtration do you run one after the other? Do you

We have tried air drying (using shop air) our SMT stencil post sonic cleaning. This technique only "pushes" the water droplet around to the other side of the stencil. Air drying causes the "Invar" stencils to rust as the water sits on the stencil sur

Yes, it is important to ensure blade pressure over stencil is uniformly distributed across the entire length of blade. Such is possible only if the stencil is firmly supported from below, which during printing is done by the presence of the PCB itsel

Any suggestions/experience in repairing an old electrovert stainless wave solder pot? We have been running SN100C in this pot for a few years, and it developed a small leak along the weld in one corner. I am wondering of the best repair methods, an
