Our facility is 5 years in the current configuration. We are in 75K sq/ft and went with glued down fully conductive tile throughout the factory. Looks great after 5 years, and we have a lot of traffic. In this setup, those same high traffic area

Chances are you are using this as a 2.5V voltage reference for the feedback on your regulator. One thing that isn't clear is exactly what failure you are seeing. Please specify the nature of the failure. Is your power bus out of spec? I really ca

The vent is there for reasons as the name implies. It's a safety feature to prevent the cap from exploding if over-tasked. Yes, without the relief on the end, the caps have a potential to become missiles when they go. I had one go off when my hand

Most times when the machine oscillates when closing the doors it will be a problem with the digital i/o cards. I would check that the dip switch settings are correct. If they are correct i would look at replacing both of the cards. The boards are sub

It sounds like a bit too much solder on the PWB, caused by too large a pad for the lead it will contain. In that case solder reduction is the way to move forward. What are the options there? 1. New stencil or stencils - (not desirable) 2. Increas

Thank you guys. As we are speaking I keep examine the problem and here is what I got so far. 1. I measured the temperatures on my profile and the lead is hotter than the board. The lead goes 12 seconds earlier than the pad and is taking the solder.

I hate to say this but in all probability this wont work. I have built real strain gages and they depend on the change(Co-effiecent) of resistence with strain(or Stretch). since you are connecting you elements up with copper wire it will frm part of

Damn near impossible. You need to see a real change in the difference between the 2 elements you are reading. So to give yourself any hope run 2 long traces one top one bottom up the length of the board. Then compare to 2 wriggly traces at one end (o

Hello, We had just bought new 44mm one for wide ZIF connectors etc. The problem is that JUKI don't even thin about picking something from it. 44mm option is available in component packaging style window. Tray feeder is choose for "44mm emboss 12mm (

From the picture I would say the problem lies with the PWB manufacturer. It looks as though some part of the plating process was not optimal during the PWB production run, and you have the resulting discoloration following the reflow process. What
