PCB boards are widely used in electronics, computers, electrical appliances, mechanical equipment, and other industries. They serve as support for components and are primarily used to connect components to provide electricity. Among them, 4-layer and 6-layer circuit boards are the most common and widely used. Depending on the industry application, different levels of PCB board layers can be selected. Let’s explore the basic knowledge of PCB boards and the process of PCB board corrosion.
Printed Circuit Board:
Also known as a printed circuit board, PCB board for short, or PWB (printed wiring board) for short, is made using an insulating board as the base material. It is cut into a specific size with at least one conductive pattern attached to it. Holes, such as component holes, fastening holes, and metallized holes, are used to replace the chassis of electronic components in previous devices and enable the interconnection between electronic components. Because this board is produced through electronic printing, it is referred to as a “printed” circuit board. It is not accurate to call it a “printed circuit board” as there are no “printed components” on the board, only wiring.
The PCB board is a vital electronic component and provides support for electronic components. Automatic soldering machines offer technical support for the soldering of PCB boards, enabling the advancement of electronic components. However, automatic soldering vendors have been plagued by the issue of PCB circuit board corrosion. WellCircuits Limited has conducted research and resolved the problem of PCB circuit board corrosion through years of accumulated experience.
What is the process of PCB board corrosion?
The corrosive liquid typically consists of ferric chloride and water. Ferric chloride is a yellowish solid that readily absorbs moisture from the air, requiring sealed storage. When preparing the ferric chloride solution, a ratio of 40% ferric chloride and 60% water is generally used. Using more ferric chloride or warm water (not hot water to prevent paint damage) can accelerate the reaction (Note: ferric chloride is corrosive, do not let it come into contact with skin or clothing). Use an inexpensive plastic basin as the reaction vessel for the circuit board.
Begin the corrosion process of the PCB board from the edge. Once the unpainted copper foil is corroded, promptly remove the circuit board to prevent erosion of useful circuits. Rinse with clean water at this point and remove the paint using bamboo chips or rinse with hot water if scratching is difficult. Dry the board, polish it with sandpaper to reveal shiny copper foil, and your printed circuit board is now ready. To preserve the results, polished PCB boards are often coated with a rosin solution, aiding in soldering and preventing oxidation.
