Troubleshooting Static Sensitive Devices

Certain precautions must be taken when working with static-sensitive devices, e.g., microprocessors, field-effect transistors (FET), complementary metal-oxide semiconductors (CMOS), and other large-scale integration (LSI) devices that use metal-oxide semiconductor (MOS) technology. Static charge buildup in a person's body or leakage from an improperly grounded soldering iron can cause static-sensitive device failure. Before handling a static-sensitive device or a PCB with such devices attached...

Introduction

Xybots is a one- or two-player game with a continuous buy-in feature allowing players to join in at any time. A color-coded control panel (left player blue and right player green) and game character allows for instant identification by players. Each player controls a special joystick and two buttons. The joystick is eight-way directional with an independently turning knob for left and right turns. Players use a blaster to fire upon the many Xybots in the maze. A button is located on each side...

Removing Integrated Circuits

The easiest and safest method for removing soldered-in integrated circuits (IC) from a PCB is to cut off each pin as close to the IC case as possible with a tip dyke (diagonal cutter) as shown in Figure 4-1. Use the proper soldering iron as previously described under Soldering Techniques. Then, to avoid excessive heat buildup in one area of the PCB, apply heat directly to each pin in a random order. Remove the loosened pin with the tip of the soldering iron or a needle-nose pliers as shown in...
