Hi, Greetings!!! Iam a service engineer working as a free lancer. Currently iam working on a PCB where i need to replace a SMD component, i think its a transistor but iam not sure as i dont have the original schematic. I have the image with device

We are using Wertheim SMT Reflow oven.We are facing component drop issue from bottom side while top side is running. The drop components is diode,3 pin transitor which not even too heavy..We are also getting tombstone in bottom side Chip capacitor wh

The DEK Gridlock system should have rubber pads on top of the metal posts. We had them in our old Dek machines but upgraded to the fully automatic ones on our O3iX machines (Grid Lok) The manual ones can be tricky to set up and requires you to have

I would always have top and bottom preheaters in a solderwave machine. Even if you can make it work without them, it's better to heat both sides of a board then just one. Far less stress on the parts you are soldering. Plus you may need it one day fo

Yep, done it previously with a multipot machine. Using with wirefeed to top up the pots means you only have a contamintion risk when you fit a new top up reel. Used separate nozzles for both, but theoretically using titanium nozzles would mean no c

The 2 big ribbon cables, on top of the X wagon. They run from the booster board, in the back, to the board on top of the X-wagon. They wear out and need to be replaced, periodically. Since, the tool cycle works, the Z-motion is probably working ok. I

| I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the ant

Thank you Steve for your input it was very usefull. I think I skipped a few pertinant details on my initial message though, the component which we found the flux contamination on was on the top side of the board, I was curious if the flux could come

If your operation is hi-mix low-volume, consider taking a look at some of the bench-top units out there. They are lower cost but can give similar performance as higher cost in-line systems. Some of the bench-tops cannot do solder fillet inspections t
