"Made in Germany" or just a German address? Here's how to tell where your printed circuit boards are actually manufactured.

A German website, a German phone number, and a German flag: Does that mean the circuit board is also manufactured in Germany? Not necessarily.

Many manufacturers that produce in Asia operate locally in the German market. However, a German flag, a German phone number, a .de domain, a German sales department, or a German branch office are not, in themselves, proof of production in Germany. Therefore, a different question is crucial for purchasing decisions:

Where is the circuit board actually manufactured?

Because a supplier with a German branch and Asian production is something different than a printed circuit board manufacturer like Precoplat with its own production facilities in Germany. This differentiation should be recognized, especially when comparing prices, managing supply chains, ensuring data security, or dealing with short-term technical changes.

Why this distinction is important when comparing prices

Offers from Asia can be significantly cheaper. However, the printed circuit board industry there operates under different conditions: very high production volumes, highly concentrated supply chains, lower environmental standards and energy/labor costs, as well as substantial subsidies.

This is neither good nor bad in itself. It is simply a different industrial structure.

However, price comparisons become problematic when a customer believes they are comparing two European manufacturing models, but is actually comparing a German-made product with one from a supplier whose production is largely in Asia. In that case, it's easy to compare apples and oranges. Andreas Brüggen, Managing Director of Precoplat, emphasizes the production location as an essential component of a fair comparison of offers: "If a supplier sells in Germany but has the circuit board manufactured in Asia, that's no comparison to German manufacturing. The production location should be just as transparent as the price and delivery time."

Therefore, a clear indication of origin is the first reliable indication of actual German manufacturing. Are the offered circuit boards, for example, labelled "Made in Germany"? This designation is more than just a pretty German flag. According to legal precedent, the essential manufacturing steps that give an industrial product its key properties must take place in Germany. However, purchased raw materials or semi-finished products do not fundamentally preclude "Made in Germany." Precoplat This origin is deliberately stated unambiguously: The circuit boards of Precoplat are manufactured exclusively in Germany. The reasons behind this decision are explained in detail under Made in Germany Precoplat explained.

For Katharina Völker, Managing Director of PrecoplatTherefore, a statement of origin also includes the corresponding traceability: "Made in Germany should not be a promise that the customer simply has to believe. With Precoplat "It can be shown specifically where the printed circuit boards are manufactured: at our own production site in Krefeld." Whether such a statement is actually plausible can be easily checked with just a few points.

The quick origin check for printed circuit boards:

1. Does the printed circuit board explicitly state "Made in Germany"?

Not "German Engineering", "German Service" or "European Provider", but a clear statement about Manufacturing of the product.

For Precoplat: Yes.

2. Is a specific production site named?

A manufacturer should not only state its company headquarters, but also be able to explain, where production takes place.

For Precoplat The answer is: Oberdießemer Straße 15 in Krefeld.

Those who want to take a very pragmatic approach can even view the location from the air: Precoplat-Production on Google EarthA satellite image is of course not a certificate of origin. But it is a surprisingly simple plausibility check to verify whether an address actually represents an industrial production site.

3. Are the company's own manufacturing processes shown transparently?

Those who produce their own goods should also be able to provide insights into their own manufacturing process.

Production images, insights into individual manufacturing steps, and company or press reports can reveal which processes are actually carried out in-house. This is particularly useful for printed circuit boards, allowing companies to verify whether processes such as multilayer manufacturing, drilling and milling, electroplating, structuring, solder mask application, surface finishing, or testing procedures are part of their in-house production.

Precoplat The company presents its manufacturing on its own website and regularly in company articles and press releases.

4. Are technical data, quality standards and certificates publicly verifiable?

The more transparently a manufacturer documents its technical capabilities, the easier it is to assess whether the stated level of vertical integration is plausible.

For Precoplat is this in Download Center comprehensibly. Published there Precoplat including technical delivery conditions, design rules, multilayer layer structures and certificates.

Four yeses? Then there's already a strong case for actually having your own production facility.

German raw materials are not required for "Made in Germany".

One point is occasionally misunderstood regarding the topic of "Made in Germany".

The circuit boards of Precoplat The raw materials are not exclusively of German origin. FR4 laminates, copper foils, chemicals, and other pre-materials are part of international supply chains. This is unavoidable, as many components can no longer be sourced within Europe.

What is crucial for industrial products is where the key value-determining manufacturing steps take place. For Precoplat great from these raw materials Unpopulated printed circuit boards manufactured in KrefeldFrom technical data verification to the actual printed circuit board manufacturing and quality assurance, the crucial processes remain at the site.

International procurement is not inherently wrong. For certain requirements, it is absolutely economically sensible and without alternative.

But: The customer should know what they are buying and where it is produced.

Choosing an Asian manufacturer is a logical procurement decision. However, those who deliberately want to source a printed circuit board from Germany or Western Europe should be certain that the product actually comes from such a location.

Conclusion: Don't just look at the flag

Registering a German domain is quick and easy.
A German flag can be quickly placed on a website.
A German sales office can also be opened.

However, complex printed circuit board manufacturing in Germany is not possible.

Anyone who values ​​"Made in Germany" should therefore definitely not forgo a brief background check.

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.
