Types of metal plating process

Types of metal plating process The metal plating process is of two different types: Electroplating and electroless plating. While electroplating requires electrical current, electroless plating involves dipping the component in a liquid solution to bring about the desired reaction. Both the processes have their own pros and cons. The choice of plating method is determined …

Related effects of electroplating

A technology that uses the principle of an electrolytic cell to deposit a metal coating with good adhesion but with different properties from the base material on mechanical products. The electroplating layer is more uniform than the hot dip layer, and is generally thinner, ranging from a few microns to tens of microns. Through electroplating, …

PCB Stripping Process

PCB Stripping Process Post etching process, the copper present on the PCB gets covered either by electroplated tin or tin/lead. You can use concentrated Nitric acid to remove the tin. Nitric acid is very effective in removing tin, and does not damage the copper circuit tracks below the tin metal. Thus, now you have a …

PCB ETCIHNG PROCESS

PCB Etching Process While making PCBs, a layer of copper is added on the substrate. Sometimes, both the sides of the substrate are covered with copper layers. PCB etching process is carried out to get rid of the excessive copper, and only the required copper traces are left behind after the etching process. The etching …

wet PCB etching advantage analyze

Advantages of wet PCB etching The most important advantage of wet PCB etching is that it can be conducted in a normal atmospheric environment. High etching rate Low operational cost High selectivity: wet etching can be used to etch off a wide range of materials. Ease of equipment maintenance Disadvantages of wet PCB etching   …

THE CONSTRUCTION OF DOUBLE SIDED PTH

DOUBLE SIDED PTH Multiple materials are available for board manufacturing. The most used is FR4, which is a costly material, but CEM3 is also possible. The traditional method of making the electrical connections between the top and bottom circuits is to drill holes plated with a conductive material (usually copper). The holes can also be …

The CNC drill machine

CNC drill machine: The drilling machine is a preprogrammed Computer Numerically Controlled (CNC) machine. The drill takes place based on the XY coordinates fed into the CNC system. The spindles rotate at a high RPM and ensure an accurate drill hole in the PCB. When the spindle rotates at a rapid speed, heat is generated …
