A GOOD SOLDER JOINT is bright and shiny with no cracks or pits.When REPLACING DIPs, TOs, AND FLAT PACKS, make certain that pins are placed in theproper position.COMPONENT LEADS may be clipped prior to removal only if the part is known to be bad or ifnormal removal will result in board damage.The technician must determine through INSPECTION what method of repair is necessary for theboard.3-48
ELECTROSTATIC DISCHARGE (ESD) can damage or destroy many types of electroniccomponents including integrated circuits and discrete components.Special handling is required for ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) devicesor components.USE PRESCRIBED SAFETY PRECAUTIONS when you use power tools, soldering irons,cleaning solvents, and aerosol dispensers.3-49
