Basically, the charge curve of a nicad cell isn't particularly linear. Your length of time is more dependant on the amperage rating of your cell. There's a difference between a 1.4 Amp and a 2.2 Amp capacity. As a nicad charges the bulk of the cha

What would happen if a 2 volt solar cell was hooked through a diode into to a 3.6 volt nicad (3xAA)? would it charge it at all? just a bit but never fully? would battery deliver 3.6 volt after charging? If left long enough would it charge fully?

You weren't clear on the type of gauge that you're using. Strain gauge load cells are the most common. These load cells have two gauges. The orientation of the gauges affects cell performance characteristics. * Temperature compensated: Temperature

By "placement pressure" I assume you mean force. I don't know of placement machines that have transducers mounted on the placement spindles that actually measure force. We made a board with a force sensor mounted through a hole so that it was the sa

We built our own coating system by mounting a Universal Robots UR5 to an edge conveyor between a magazine unloader and magazine loader. The robot has a needle dispenser on the head. We chose a needle dispense process to avoid aerosols and complex ven

99.70% mounting rates. 4.Make sure your machine can handle the recognition of this components (shape & height) usually height measuring(pick up error) is the biggest problem with resistors. 5.When mounting a real PCB you can have spacings up to 0.3mm

Start with a load cell (force sensor), you will need one that can handle the force range you will be placing. Someone please correct me on this if I'm wrong but I seem to recall that placement force runs in the range of a couple hundred grams. Chec

What is the method of Reflow profiling for a duel line reflow?? I am planning to have a duel line Reflow oven for cell phone production. As 2 types of PCB ( Top + Bottom) will enter machine at the same time and both will have different numbers of mou

I need ideas for mounting without a connector a small pwa daughter card vertically to another pwa. I have seen u shaped clips for the edge of the card which allow you to insert and wave solder the card into the mother board. How are these clips atom

Hi, I have a question about charging up batteries. I have two batteries in series, they are NiMH PCB mounted rechargable batteries that are used for battery backups etc. I want to be able to recharge these batteries, so I wont have to buy new ones
