I'm investigating heat transfer by 1st order approximation between PCB and ambient air via encapsulate material (epoxy or gel or silicone), they have thermal conductivity of 0.2W/C but it hard to find specific heat capacity and density. Has anyone

Hi Yes it is common to design for more uniform heat transfer during the soldering phase or even during the operation phase. It all depends on how bad the problem is during automated assembly or during usage. The only difficulty is that the designer

Hi Folks, My Production runs a uBGA-liken product, and uses Pallets to support the 0.8mm thick pcb, during the SMT + reflow oven process. Process/QA see occurs: 1) 0402 unsolder? 2) 0402 tombstone? 3) "uBGA" poor-visual joints (dry joints)? Took

Q1. What kind of labels/ink/sharpe can be used under conformal coating without disolving etc...? A1. While we're not familiar with the conformal coat you have selected, this might help. Label selection: The following chemically durable materials are

I'm looking into labeling solutions for our PCB's. I've got it narrowed down to the label and the ribbon to match our thermal and cleaning processes, now I'm looking into the best overall industrial style printers. What brand and model thermal prin

We use Zebra printers 170xii. If you buy used you can get them for a relatively low cost ( couple hundred $$). You will need to find software to work with the printer. We use Bar One. Brady Labels supplies a full line of thermal printable labels & ri

| Does anyone have experience with placing heat sinks on BGAs? I have limited experience with PSA (pressure sensitive adhesives)heat sinks, and am interested with the possibility of a clip-on device. I am specifically concerned with ease of assembl

ECD's OvenRIDER is the only instrument I know that can measure thermal transfer efficiency of a an oven. I suppose it would work for environmental chambers too. This instrument has thermocouples to measure ambient temp of oven zones and well as hi-ma
