I agree with Russ. The problem is your thermal isolation is so small 1/16 inch. Also, most ovens measure temperaure in the plenum. You don't solder in the plenum. Therefore, you have a intermidiate "zone" temp. mixing between the top and bottom

I was afraid so. Hand soldering wires in general is not difficult, but with your constraint of the space restriction it does make fairly hard to do. I am assuming you have a 2 sided board and stranded copper wire. So once solder starts to flow, th

sant, When I worked in contract manufacturing, I used Air Vac or SRT systems which are rather large units. They are great for larger boards and BGA's. In my OEM life, I prefer smaller desk top units, which are more adapted to small boards with small

Thinking about this auto-mode on Grid-Lok..... Ok, the board is warped, lets say positively, the pins conform to the warped board... what about the effect on top side and squeegee pressure? It will be much higher and could damage stencils, right? Pos

Siemens is the General Electric of Europe. Like GE, Siemens typically is in the top 3 positions ($ market share and profit) or they exit the business. In total revenue I expect Siemens to be in the top 2-3 globally. In units I expect Yamaha has the

Imagine you put two 8mm feeders on the rear feeder plate, they are about the same distance apart as the length of your tray. On top of these feeders are two slotted arms that allow you to move the arms towards the moveable rail. You place your tray o

I experienced this with a high-mass capacitor. I was able to turn down the bottom-side convection (around 50�C lower than each of the top-side heaters), and able to NOT lose any parts. I got the bottom-side part just slightly over liquidus, and min

Are you using nocleans, especially when you get to SMT? Years ago, I had OA wave flux get into vias that were plugged from the top under parts. It is really difficult to clean small, high aspect ratio vias. Cross sections showed that the copper in
