Semi-finished sourcing · For buyers abroad

From bare board to finished assembly.

You don't manage ten vendors across the Pacific — you brief one. BISUGI SOLUTION turns specs into PCBs, populated PCBAs, modules and complete assemblies, then ships them ready.

2 lineselectronics & metal

Electronics line

One chain. Four stages. Zero hand-off gaps.

Most buyers stitch the chain together themselves — a board house here, an assembler there. We hold the whole sequence under one quote and one point of accountability.

STAGE 01

PCB

Rigid, flex, rigid-flex, HDI and metal-core bare boards — single-sided to 36 layers. Full range

STAGE 02

PCBA

SMT and through-hole population. Components sourced, placed, reflowed, inspected.

STAGE 03

PCBA Module

Functional sub-assemblies — tested, firmware-loaded, ready to drop into your product.

STAGE 04

Full Assembly

Box-build: enclosure, wiring, final test, packaging — shipped as a finished unit.

PCB capability

Which boards, exactly.

A "PCB" line on a website tells you nothing. Below is the actual process window our contracted fabrication lines run today. If your board fits inside it, we can quote it.

Rigid multilayer

Single-sided to 36 layers. FR-4, high-Tg FR-4 (170 / 180 °C) and halogen-free builds.

HDI

Blind and buried vias up to 3+N+3, laser microvias from 0.075 mm, resin-filled and capped.

Flex & rigid-flex

FPC and rigid-flex stack-ups — for products that fold, fit tight, or live with vibration.

Metal-core

Aluminum-base and copper-base boards for thermal loads — LED, power, automotive.

High-frequency

Rogers and ISOLA laminates with controlled impedance, Polar-tested to ±5%.

Heavy copper

Up to 4 oz copper for power conversion and high-current boards.

Layer count: 1 – 36 layers, including buried / blind via structures
Max board size: up to 762 × 620 mm
Board thickness: 0.2 – 5.0 mm finished
Min track / gap: 0.064 mm / 0.064 mm (2.5 / 2.5 mil)
Min hole size: 0.075 mm laser · 0.15 mm mechanical
Copper weight: 1/3 oz – 4 oz
Impedance control: ±5 – 10%, coupon-tested on calibrated Polar equipment
Materials: FR-4 · high-Tg FR-4 · halogen-free · CEM-1/3 · Rogers · ISOLA · aluminum / copper base
Surface finish: Lead-free HASL · ENIG · ENEPIG · immersion Ag / Sn · OSP · hard gold fingers to 50 µ″ · selective gold · carbon ink
Solder mask: 13 colours incl. matte finishes · min dam 0.075 mm
Testing: 100% electrical test · AOI · flying probe · impedance coupons

Outside the window? Ask anyway. Edge cases are quoted case by case, and the full capability sheet is available on request. The same lines currently ship boards into communications, industrial & medical, computing and automotive products.

Two production lines

Electronics and metal, under one roof of accountability.

● Metal & Machining

CNC parts · Metal 3D printing

Precision-machined components and additive metal parts — prototyping through production runs.

3 / 4 / 5-axis CNC Turning & milling Metal 3D (DMLS / SLM) Surface finishing Inspection reports

Metal 3D printing

What we actually print.

Additive metal earns its place where machining can't reach — internal channels, lattices and one-piece geometries, in batches too small to justify tooling.

Industrial heat sinks

Pin-fin and lattice geometries, conformal cooling channels — shapes machining can't reach, printed as one part.

Custom alloy fasteners

Titanium, Inconel and stainless screws in non-standard geometries. Small batches, no tooling cost.

Aircraft seat components

Weight-cut brackets, recline and armrest fittings — buy-to-fly ratios subtractive parts can't match.

Aerospace-grade thermal

Conformal heat exchangers and cold plates for power-dense electronics — internal channels, single print.

Typical powders AlSi10Mg Ti-6Al-4V Inconel 718 316L / 17-4PH

Why one partner

We don't add a middleman. We remove nine.

A single brief, a single quote, a single thread of accountability — instead of a spreadsheet of suppliers you chase across languages and time zones.

One point of accountability

From the board to the finished unit, one team owns the result. No finger-pointing between vendors.

Specs in, ready units out

Send drawings, Gerbers or a BOM. We return quoted, manufacturable, shippable hardware.

Built for buyers abroad

Communication on your hours, documentation in your language, logistics to your door.

How it works

Four steps from brief to delivery.

01 · BRIEF

Send your specs

Gerbers, BOM, drawings or a part description — whatever stage you're at.

02 · QUOTE

Get a clear price

One quote covering the full scope, with lead time and assumptions stated.

03 · BUILD

We manufacture

Sourcing, fabrication, assembly and test — managed and reported to you.

04 · SHIP

Finished & delivered

Inspected units, documentation and logistics to your destination.

Same family, different job. BISUGI CORP. sources Japan's high-performance materials. BISUGI SOLUTION turns that sourcing know-how into finished hardware for buyers abroad.
