Tools and equipment commonly used by pcba maintenance engineers include:
(a) measurement tools:
Computer: view the circuit map。
(b) zenium palladium: aluminum for measuring the voltage, current, resistance, diode values etc. Of the circuit。
Oscilloscopes: glyphs designed to detect certain signals that cannot be measured on a universal scale, such as clock signals, control signals, data transmission, circuit frequency, etc。
Pyramid power adapters: provide voltage to pcba, measure working currents, and determine the area of failure according to current size。
Welding tools:
(b) iron latte: for welding components and guidance。
Hot wind gun: tin used to heat the element to the feet to remove it from the pcb plate。
• a small tin furnace: welding and disassembly of direct plugs。
Bottom heater: provide heat to the bottom of the pcba, reduce the spread rate of the pcba and facilitate welding。
Other tools:
Magnetic magnifiers: micro-components and circuits used to observe circuit boards。
Lighting。
Pyramids: mainly used for the extraction of micro-components, especially those such as electrical resistance type 0402。
Pistol pliers, slant pliers, cutters: used for the treatment of connections and component plating on circuit boards。
programming burner : used to burn the program to chip 。
Zirconium net: for bga tin planting。
Tin ointment: for bga tin planting。
Scratch: for bga tin planting and removal of bga residue。
Multitype screwdriver: dismantling screws。
Pcba stationary vehicle: fixed pcba。
High-temperature paper: covers the high-temperature original。
Welders: increased welding mobility。
Cece: welded original。
Cleaning agents: removal of residual welding, fingerprints, stains etc。
Dust paper: wipe dirty。
Alcohol: wipe dirty。
Alcohol bottles: alcohol, detergents, welders。
Insulation boards: protect desktops from burns。
Gloves: electrostatic protection。
Static rings: electrostatic protection。
Mask: prevention of inhalation of welding gas。
Wind pump: welding residual gas。
These tools and equipment play a critical role in pcba maintenance and can assist engineers in the testing, repair and maintenance of circuit boards。
