Wire board manufacturing involves a lot of pieces, steps and processes that all have to come together with precision to create a reliable finished product. Any contaminant created in the manufacturing process that aren’t filtered out can affect the short- and long-term performance of circuit boards.
From film generation to electroless copper plating and screen printing to applying solder masks, 3M filtration solutions can help ensure your wire boards will meet your performance needs.
We’re here to help. For more than 100 years, 3M has partnered with our customers to develop innovative filtration and purification products to help in their manufacturing processes.
Ultrapure water (UPW) is mainly used to remove defect-causing contaminants from the surface and to rinse or clean wire boards after they have been exposed to chemicals during various processes.
3M’s filtration products provide the particle reduction needed to meet the strict requirements of the electronics industry.
It’s critical to remove particles from your plating solution to prevent bath contamination. With the right filtration, you can help greatly reduce the amounts of contaminants in your plating solutions.
3M has the filtration solutions you need to help remove contaminants before and during the plating process.
Your wire board manufacturing process requires large amounts of chemicals, which invariably generates substantial volumes of wastewater. The different fabrication processes create a variety of wastewater contaminants that need to be reduced to meet required levels.
3M has filtration solutions designed to help you filter your wastewater to protect the environment and meet increasingly stringent discharge requirements.
3M™ Liqui-Cel™ Membrane Contactors are used in a variety of gas transfer applications to strip dissolved gases from aqueous fluids. In one specific use, ammonia gas is stripped from wastewater streams with a high concentration of ammonia, diffuses across the wall of a hollow fiber membrane, and is directly absorbed into a reactive acid solution.
This simultaneous removal and recovery of ammonia is possible in a single device. This process is called TMCS (Transmembrane Chemisorption).
Digital inkjet printing has been introduced in recent years as an alternative production process to traditional printing technologies to improve the flexibility of printed wire board manufacturing. Today, thanks to digital inkjet printing, smaller series can be produced for reasonable cost and on short term.
For optimization of printing speed and yield, degassing of the inks -conductive or isolating- can be effected upstream to the printheads by 3M™ Liqui-Cel™ SP membrane degassers.
