HDI PCB Manufacturer & Exporter in the Sweden Market

We offer daily express courier shipments via DHL Express, FedEx, and UPS with direct air routes from Shenzhen/Hong Kong to Stockholm Arlanda (ARN) and Gothenburg Landvetter (GOT). Typical air express transit takes between 3 to 5 business days. For volume industrial production, we offer air and sea freight with Delivered Duty Paid (DDP) or Delivered at Place (DAP) Incoterms 2020. Under DDP terms, our logistics partners manage customs clearance and Swedish VAT (Moms) collection, delivering shipments straight to your receiving dock in Kista, Gothenburg, Malmö, or Linköping with zero customs delays.

To perform a full DFM and signal integrity evaluation, please provide your complete Gerber package (RS-274X or ODB++ format) including NC drill files, fabrication drawing specifying layer stack-up, dielectric thickness, copper weights, solder mask color, and finish type. If your design contains controlled impedance lines, provide a clear impedance table detailing target ohms, trace widths, reference planes, and allowable tolerance (±10% or ±5%). For turnkey PCBA orders, include your Bill of Materials (BOM) with exact manufacturer part numbers and centroid (pick-and-place) coordinates. Our CAM engineering team in Shenzhen reviews files within 12 hours and returns a comprehensive DFM query sheet before starting production.

Microvia reliability in cold climates (-40°C to +85°C) depends fundamentally on copper ductility, aspect ratio, and base laminate Z-axis coefficient of thermal expansion (CTE). We only procure premium high-Tg laminates (Shengyi S1000-2M, ITEQ IT-180A, Nelco, or Panasonic Megtron) engineered with a low Z-axis CTE of ≤ 2.5% below Tg. Our microvia plating utilizes specialized pulse reverse plating baths that deposit smooth, void-free electrolytic copper with a minimum tensile elongation of 18%. Every production batch undergoes microsection metallurgical analysis, automated cross-section testing, and thermal stress testing (6× solder float at 288°C according to IPC-TM-650 2.6.8).

Yes. Operating from our Shenzhen manufacturing center gives us immediate direct access to tier-1 authorized distributors (including DigiKey, Mouser, Arrow, and domestic authorized semiconductor franchises). For parts with extended lead times or obsolete silicon, our component engineering staff suggests pin-to-pin, functionally equivalent cross-references. Any proposed substitute must be accompanied by comprehensive datasheets and requires explicit, written approval from your engineering team before purchase. We enforce incoming visual, X-ray, and decapsulation testing to verify authenticity and prevent counterfeit silicon from entering assembly lines.

We treat customer CAD data and proprietary Gerber files with bank-level security. We regularly sign bilateral Non-Disclosure Agreements (NDAs) governed under European or Swedish commercial legal precedents prior to receiving schematics. All customer project documentation is stored on encrypted, access-restricted internal servers, partitioned so that only authorized production engineers and CAM operators can access fabrication files. We have served overseas hardware engineering clients for over 8 consecutive years with an unblemished record of intellectual property respect and zero IP leakage.
