How To Avoid Environmental Pollution PCB manufacturing

Environmental Pollution PCB manufacturing1

Despite the tremendous advantages offered by the PCBs to the engineering industry, a significant quantity of toxic waste with the potential of Environmental Pollution PCB manufacturing is released as an inevitable byproduct.

The PCBs are made with various materials to forge them into require structures with custom parameters.

Since all of the material used in PCBs undergoes various processing before being used in PCB, the pollution level increases.

1.Environmental Pollution PCB manufacturing

For example, let us consider the epoxy board, made from glass fibres or plastic sheets merged with industrial-grade epoxy adhesives.

To the merger, each sheet is treated using various concentrated chemicals to get rid of the residues. The excess solution is cleansed with another chemical solution to make it PCB friendly. This entire process releases a chemical that is toxic to the environment.

Even the raw material used in making the epoxy boards under chemical process is a chain of toxic chemical processes from earthed minerals to functional PCB. The flux used to bond the solder paste usually contains 30+ chemical and petroleum products that emit toxic gases oily residues when heated. Filtration and containment techniques are used to arrest these effects, but they are not perfect such that a significant quantity is released anyways.

2.How to avoid or reduce it?

IPC standards enlist the allowable amount of chemicals to be discarded into the environment. A quality board must have almost no post-manufacturing emissions and residues that may harm the user. Due to pollution, heavy metals like lead are prohibited from using almost every electronic product to minimize the toxic effect.

New and improved methods that can ease the manufacturing process and cause less pollution to the environment are continuously evolving every day.

Recycling can also reduce pollution.

Our professional engineering support saves our customers a lot of trouble and loss. >>>>>> After you place the order, our engineer will conduct technical reviews to make sure the parts can be mounted well/correctly on the boards. We will check if the component packages match well with the Gerber footprints, if the part numbers you provided match well with the descriptions, and if the polarity is clearly marked. >>>>> When your design is ready, please send your Gerber and BOM so we can quote and start!
