PRINTED CIRCUIT BOARDS (PCB)

costs being a bit higher.What are they? The boards are conventional, 1 oz. copper PCboards with a Fiberglas substrate. The copper is coated with a light sensi-tive chemical that is often called a resist or a sensitizer. When this coat-ing is exposed to enough ultraviolet light, it will rinse[r]

Step 3. Expose to the Datak ER-39 bulb at a distance of 24" for1-1/2 minutes (4 minutes if a paper positive).Special note: For circuits larger than 4" X 4", you may find the outercomers not fully exposed. For larger boards, you may suspend theER-39 bulbso that it swings freely on its power co[r]

The SMPS (Switch Mode Power Supply) circuit is illustrated as a block, whose power source is connected to the DC bus. The SMPS transforms the DC bus voltage into several different DC low voltage outputs. It supplies +5V for the MCU and its peripheral circuits, +12V DC for the cooling fan, and[r]

This is especially good news if you’re using a temperature sensor in a plastic package, since thermal conduc-tion for such a device is through the leads. Locate the sensor as close as possible to the amplifier’s leads. If theamplifier has a ground pin, place the sensors ground pin right next to that[r]

times the equipment will not be damaged, but the data damage can be very costly and time-consuming to correct. To even start to locate these glitches, an oscilloscope is a must. How-ever, even with the best equipment a stray glitch is a “tough nut” to crack.Some of these spikes will occur in the pow[r]

Make sure that butt joints in the decking do not occur on the same joist for 2 consecutive rows. Make sure they are staggered for both aesthetic and structural reasons. STEPS 1. When installing the decking boards, you can use screws or galvanized nails. Use 2 screws or nails where[r]

We used an SOC platform built in XILINX SPARTAN-3 (SP3) [21] as a Web server and digital signal processing (DSP) unit which was implemented by using C language in order to transmit the physiological information to Web page or nursing center through the TCP/IP with a cable RJ-45.
