The assembly process involves activity before you get to reflow. Reflowing is the easy part. Putting paste down and placing parts in wet paste is the terrifying part. Benchtop reflow ovens can be a real handy tool for small production but with the g

Hi SMT Engr With a double-header connector do you mean Double Level Right Angled Header Connector. If so there is a big difference in heat sinking capacity between the two rows, as where the pins of the top connector absorbes twice as much heat as t

I've tried a different lot of the same double header connector (yes its double level right angled header conector) twice but nothing has improved. I've also suspected that top row of the connector has greater heat sinking capacity (which should hold

So, someone is going to get a chance to buy a nice and shiny oven, eh? Summary from my notes of old thread on SMTnet: Some people melt sugar and use that solution to clean cooked-on flux residue. Dissolve sugar into warm water, spray it on the area t

ALso, coming to the convection the DIMA service group said : "Its full convection in the top zones. The bottom zones are heating elements mounted underneath a thick aluminium plate. So not full IR, but the head is coming from the heated aluminium p

What type of aluminium tape should be used? I tried one, but it wouldn't stick to the board at reflow temperatures.

We'have been working on an issue regarding aluminium capacitor placement in PCB. In fact, we have twisted (shifted) capacitors. Through root causes analysis, we confirmed that this phenomenon is happening during reflow process (no issue on placement

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

We have had this experience in China. Some of our customer produce aluminium radiator. They always ask us to design this type reflow oven for it.Because the large desire of the heat,we have to design the oven at a higher temperature.It's almost meet

Sorry looking at your profile again and considering its Aluminium substrate I would opt for an increase to the preheat or introduce a soak to the profile to get the PCB up to reflow. Try soaking between 175 - 200C sufficient enough to heat the whole
