Creating new things from old – PRECOPLAT supports Emmaus Krefeld

As a company rooted in Krefeld, PRECOPLAT is committed not only to high-quality printed circuit boards, but also to sustainable and social interaction. The Emmaus Community Krefeld e.V. recently visited us and accepted a donation of decommissioned office and IT equipment. Instead of being stored unused or disposed of, these devices are now finding new uses in a social context.

Precoplat & Emmaus: Sustainability meets solidarity

Sustainability is for Precoplat Not only an issue in the production process, but also in the use of resources and in the social environment. The devices were picked up directly from our site – uncomplicated, targeted, and with a clear purpose: They will be distributed through the Emmaus second-hand market or fund projects that support people in difficult life situations.

“What has served its purpose for companies can still have a positive impact elsewhere,” says Andreas Brüggen, Managing Director of Precoplat Präzisions-Leiterplatten-Technik GmbH. "We were particularly impressed by Emmaus' philosophy: not a one-way street of support, but genuine participation through shared work, life, and commitment. We are happy to support this principle."

Emmaus Krefeld – Help for self-help

At first glance, Emmaus Krefeld might simply be mistaken for a large second-hand store—but there's much more to it than that. The Emmaus Community Krefeld e. V. is a non-profit living and working community that has been offering new perspectives to people in difficult social situations since 1992.

The focus is particularly on the formerly homeless: Emmaus combats poverty and exclusion not through subsidies, but through helping people help themselves. In concrete terms, this means that the community offers housing and meaningful work – rather than mere charity.

A large second-hand market (over 1.000 m² of hall space) operates in Krefeld, where donated furniture, electrical appliances, clothing, books, and more, either rescued from house clearances or donated from house clearances, are sold at low prices. The community uses the proceeds to finance itself and its social projects.

“Living together, working together, sharing together, getting involved” – this is the motto of the Emmaus community.

The activities of Emmaus Krefeld are diverse:

  • Second-hand market: In a hall of over 1.000 m², donated furniture, household goods, books, clothing and much more are sorted, repaired and offered at fair prices.
  • Apartment clearances & clearing out: The Emmaus team handles household clearances and collects salvageable furniture and items. Anything still usable is resold in the store or donated to those in need.
  • Scrap metal recycling: Even scrap metal is recycled – Emmaus Krefeld collects scrap metal from private individuals and businesses and sells it to recycling companies. This turns what appears to be waste into a valuable contribution to a good cause.
  • Social aid projects: For example, the community runs the day center “Die Brücke” for those in need on Tannenstraße in Krefeld and organizes soup distributions for the homeless.

All of these activities pursue a clear goal: to give people in need a new chance – while remaining independent of handouts or state aid. Instead, those involved create a dignified life for themselves through their own work and community – a true win-win for everyone involved.

Galvanic Nickel Gold (hard and bond gold)

Also known as hard gold plating. In contrast to the ENIG process, nickel is also used as a diffusion barrier to the copper, but the gold is deposited galvanically, i.e. with an external power source. This means that much thicker layers of 0,8 - 5 µ can be achieved. This "hard gold" is used for circuit boards with connector strips that are plugged in multiple times. The thicker the gold, the higher the number of plug-in cycles (example: 0,4 µ Au = 20 plug-in cycles, 2 µ = 500 plug-in cycles).

OSP (Organic Surface Protection)

OSP is an organic solution that is selectively deposited on solderable copper surfaces with a layer thickness of 0,02 to 0,06 µ using an immersion or rinsing bath. The surface is flat and is well suited for fine SMD assembly. Multiple soldering processes are not possible because the transparent layer decomposes at temperatures above 150 °C.

The shelf life is limited to 6 months.

Chemical silver (chem Ag.)

Chemical silver is a metallic, highly re-solderable surface with a layer thickness of 0,15 - 0,45 µ that is deposited on soldering points without external current (similar to the chemical tin process). The surface is flat and is well suited for SMD assembly.

A storage period of up to 6 months is possible. Similar to chemical tin, the surface loses its solderability due to fluctuations in ambient temperature and humidity. The surfaces must under no circumstances come into contact with materials containing sulphur (such as certain types of wrapping paper).

Chemical tin (chem. Sn)

Chemical tin is a metallic, very easy to solder finish. A thin layer of approx. 0,8 - 1,2 µ tin is deposited without external current on the copper of the soldering points, where it prevents the copper from oxidizing. The surface of the pads is very flat and is therefore particularly suitable for SMD, CoB and HDI and press-fit technology.

The storage time should not exceed 6 months. Humidity and temperature differences during storage can affect the solderability.

ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold)

Between the nickel and gold process steps in the ENIG process, in the ENEPIG process, additional palladium is added as an intermediate layer (0,05 – 0,25 µ thick) into the final surface without external current.

This additional layer is not only ideal for all soldering methods, but is primarily used for gold wire bonding. This process is considered a very expensive special application.

Electroless Nickel Immersion Gold (ENIG)

ENIG or chemical nickel gold is a metallic, very easy to solder finish. It is deposited on the copper layer of the soldering points with a layer thickness of 4 - 9 µ nickel and ideally 0,05 - 0,1 µ gold, which prevents the copper from oxidizing. The deposition takes place without external current using catalytic processes and the electrical potential difference (valence) of the metals used.

The surface is very flat, the multiple solderability is suitable for SMD, Cob and HDI technology as well as aluminum wire bonding and has a storage life of up to 12 months.

The surface is IPC-4552 specified and meets the current requirements of RoHs and WEE.

hot air tinning (HAL = Hot Air Leveling)

The term hot air tinning is used both for the production process and for the surface of printed circuit boards with 99,55% Sn (tin), 0,3% Ag (silver) and 0,15 -0,05% Ni (nickel). It is intended to protect the underlying copper of the soldering points from oxidation.

The circuit boards are immersed in a hot melt (> 260°C) made of the metals mentioned. The surfaces to be tinned are then blown flat with hot compressed air and the holes are blown free. The surface is very suitable for multiple soldering and can be stored for up to 12 months.

HAL is very attractive in terms of quality and price for radial assembly and single-sided SMD technology. Our solder is lead-free and complies with RoHS guidelines.
