MacDermid Alpha Releases Reel-to-Reel Indium Plating for Press-fit Connector Finishing

Reading time ( words)

MacDermid Alpha Electronics Solutions announced the release of M-Contact IN-2000 for sales worldwide. The M-Contact IN-2000 is an acid indium electroplating process for press-fit connector plating that is fully analyzable and easy to control. The indium deposit produced by the IN-2000 bath is naturally resistant to whiskering. With a wide current density range, greater than 90% plating efficiency over the life of the bath, and resistance to many different metallic bath contaminants, the IN-2000 is an excellent coating for any metal sub-layer.

“Fabricators that manufacture connectors, especially those for automotive applications, have been searching for ways to reduce reliance on tin finishes for many years. With the M-Contact IN-2000, we finally can offer an alternative to tin that provides a complete solution ready for specification,“ said Rich Bellemare, director for electrolytic metallization, circuitry solutions.

The M-Contact IN-2000 process is the latest expansion to the MacDermid Enthone brand family of connector plating chemistries that allows for highly customized stack combinations including copper, nickel, nickel alloys, palladium, tin, silver, gold and other precious metals.

Approaches to Overcome Nodules and Scratches on Wire-Bondable Plating on PCBs

07/17/2019 | Young K. Song and Vanja Bukva, Teledyne Dalsa Inc., and Ryan Wong, FTG Circuits
Initially adopted internal specifications for acceptance of printed circuit boards (PCBs) used for wire bonding was that there were no nodules or scratches allowed on the wirebond pads when inspected under 20X magnification. This paper details if wire bonding could be successfully performed over nodules and scratches and if there was a dimensional threshold where wire bonding could be successful.

Practical Implementation of Assembly Processes for Low Melting Point Solder Pastes (Part 1)

07/16/2019 | Adam Murling, Miloš Lazić, and Don Wood, Indium Corporation; and Martin Anselm, Rochester Institute of Technology
Since 2006 and the implementation of the RoHS directive, the interest in bismuth-tin solder alloys—whose melting point around 140°C is very desirable because it allows for the use of lower temperature laminate materials and reduces thermal stress on sensitive components—has only increased as the industry has searched for Pb-free alternatives to the chosen standard, SAC305, which melts at considerably higher temperatures than the incumbent tin-lead alloys.

Surface Treatment Enabling Low-Temperature Soldering to Aluminum

07/15/2019 | Divyakant Kadiwala, Averatek Corporation
An increasingly popular method to meet the need for lower cost circuitry is the use of aluminum on polyester (Al-PET) substrates. This material is gaining popularity and has found wide use in RFID tags, low-cost LED lighting, and other single-layer circuits. However, both aluminum and PET have their own constraints and require special processing to make finished circuits.
