Direct supply of advanced logic boards, mini-server platforms, and welding power driver PCBA designed for industrial electronics, IT upgrades, and power supply systems.
Berlin has transitioned from being Germany’s creative start-up hub to a focal point for deep tech, CleanTech, smart mobility, and IoT development. Key industrial complexes, such as the Adlershof Science and Technology Park and the emerging Siemensstadt Square, are housing a new generation of hardware companies designing complex electronic devices. However, local hardware innovators face a shared bottleneck: finding electronic manufacturing services (EMS) that offer both the fast prototyping agility needed in Berlin and the cost-effective volume manufacturing of Shenzhen.
From medical device developers near Charité to smart grid hardware companies in the outer districts, the demand for highly reliable, multi-layer printed circuit board assemblies (PCBAs) is rising. Crucial applications include EV charging infrastructure controllers, industrial sensor networks (IoT gateways), and high-reliability power systems. Procurement teams require PCB assembly partners that support strict quality control, such as AOI (Automated Optical Inspection), X-Ray testing for BGA components, and ICT (In-Circuit Testing).
Procuring PCBAs from offshore facilities for German integration requires strict adherence to international standards. High-reliability applications depend on IPC Class II or III standards, RoHS compliance, and REACH declaration. Velmix Technology coordinates with German engineering groups, providing quick-turn manufacturing and utilizing original chips and components sourced from authorized global distributors. This approach eliminates the risks of component obsolescence and counterfeit ICs.
In electronics manufacturing, speed and cost control are primary metrics. While Berlin provides a solid foundation for research, early-stage prototyping, and firmware development, local European SMT assembly plants struggle to match the component ecosystem speed and raw pricing scaling capacity found in Shenzhen, China. Velmix operates a 368m² modern facility optimized for high-performance memory boards and dual-channel computing assemblies, bridging these two environments.
Shenzhen's direct access to passive and active components cuts part procurement cycles from 4-6 weeks to 3-5 days. This acceleration reduces overall time-to-market for German system integrators.
Our facility integrates 100% full inspection methodologies, including signal integrity analysis, thermal cycling burn-in tests, compatibility evaluations, and structural X-Ray checking.
From minor firmware configuration changes to complete custom PCB layouts (such as copper-aluminum composite server motherboards), we provide flexible production scale adjustments.
When selecting a high-frequency PCBA supplier, physical and electrical design limits are critical. Modern high-speed computing interfaces, such as DDR5 and PCIe Gen 5/6, require micro-strip designs, controlled impedance (typically 50Ω single-ended, 90Ω or 100Ω differential), and minimal dielectric loss. Velmix addresses these requirements through the following parameters:
| PCBA / SMT Parameters | Standard Capability Range | Advanced & Custom Options |
|---|---|---|
| PCB Layer Count | 2 to 16 Layers | Up to 32 Layers (High-Density Interconnect / HDI) |
| Base Materials | FR-4, Lead-Free FR4, Halogen-Free | Rogers, Nelco, Taconic, Copper/Aluminum Composites |
| Min. Trace Width / Space | 0.1mm (4mil) | 0.075mm (3mil) for high-density routing |
| Surface Finish Options | HASL, Lead-Free HASL, OSP | ENIG (Electroless Nickel Immersion Gold), Hard Gold, Immersion Silver |
| SMT Placement Precision | 0402 components, 0.4mm pitch BGAs | 01005 passives, 0.35mm pitch BGAs, PoP (Package-on-Package) |
| Inspection Protocol | AOI (Automated Optical Inspection) | 3D X-Ray (AXI), Flying Probe Test, Functional Test (FCT), Boundary Scan |

Driven by innovation, precision manufacturing, and customer-oriented service, Velmix continues to expand its portfolio of DDR5 memory products while helping global partners build faster, more reliable, and more efficient computing systems. We are dedicated to becoming a trusted long-term supplier of premium memory solutions for customers worldwide.
Electronic systems must align with the environmental parameters of their final operational context. A motherboard deployed in a medical imaging laboratory in Berlin-Buch requires different design criteria than a heavy-duty inverter driver PCBA running in a high-temperature industrial workshop in Spandau. Below are key macro solutions that Velmix provides to match local demands.

We purchase components exclusively from authorized global distributors (Mouser, DigiKey, Arrow, Avnet) and trace them through formal manufacturer batch codes. Every completed PCBA undergoes rigorous Automated Optical Inspection (AOI) and visual checks. Upon request, we build test jigs for functional testing (FCT) and coordinate with certification labs to ensure compliance with CE mark and RoHS standards.
For prototype runs (1-10 layers), component procurement plus assembly requires 7 to 12 working days. Express air freight to Berlin Brandenburg Airport (BER) takes 3 to 5 business days. For volume manufacturing runs, standard production takes 3 to 4 weeks depending on component availability.
Yes. We specialize in handling complex substrates, including copper-aluminum composites designed to enhance heat dissipation in dual-channel high-performance servers. These composite structures improve thermal conductivity in 1U/2U server racks where high-power CPUs (like AMD EPYC or Intel Xeon) generate significant heat.
All shipments to Germany include full HS Code declarations (typically 85437090 or 84733020 for assemblies and memory modules). We provide commercial invoices, packing lists, and certificates of origin. We can ship under DDU (Delivered Duty Unpaid) or work with your shipping agent to facilitate customs clearance.
We support hardware startups and SMEs with low-volume runs. The MOQ for prototype and initial verification runs is 5 to 10 pieces. For mass production SMT runs, we offer volume-based scaling options starting at 100 pieces.
