Cable Assembly

What you actually get

A cable assembly is not “just wires.” It’s a sealed, jacketed interconnect designed to carry power, data, or mixed signals while protecting conductors from moisture, heat, abrasion, and chemicals. By contrast, a wire harness primarily organizes multiple conductors for clean routing inside protected enclosures—we supply both and help you choose based on environment and service conditions.

Typical deliverables (short list):

• Sealed cable assemblies (power, high-speed data, hybrid) for harsh environments

• Multi-branch harnesses for control panels, racks, and devices

• Overmolded connectors, strain-relief boots, and IP-rated grommets

Why BACH INDUSTRY AG

We build to the industry’s consensus workmanship rulebook: IPC/WHMA-A-620—it defines materials, methods, tests, and acceptance criteria for crimped, mechanically secured, and soldered interconnections (Classes 1/2/3). When assemblies mate to PCBAs, inspection aligns with IPC-A-610 for a coherent quality envelope. Every lot is electrically tested end-to-end; leading manufacturers treat this as table stakes.

In practice, that means:

• Documented DFM, fixtures, and first-article approval

• 100% continuity testing; HiPot/IR as specified

• Traceability packages (ballooned drawings, test records, EN 10204 3.1 on request)

Engineering that reduces risk

We start with your netlist/pinout, electrical limits, bend-radius and EMC plan, then specify conductor class, shields (foil/braid/drain), jacket (PVC, PUR, TPE, PTFE/fluoropolymer, LSZH) and connector systems. Competitor materials emphasize choosing construction to resist heat, moisture and mechanical stress; we design for those stresses explicitly. Custom lengths, colors and connector types are part of the standard scope.

Short list of add-ons: labeling (heat-shrink print, barcode/QR), serialization/UDI, routing sleeves and braided looms.

Testing & acceptance (right-sized to your risk)

• Continuity & netlist: 100% verification using learned-good fixtures

• Dielectric integrity: HiPot and insulation-resistance at specified voltages/times

• Crimps & terminations: Pull-force sampling and geometry checks per IPC/WHMA-A-620

Materials & ecosystems we support

Copper conductors from 30 AWG fine-strand to high-current gauges; twisted pairs, ribbon/FFC, coax/RF; shields to 85% braid + full-foil; jackets from commodity PVC to high-performance fluoropolymers. We maintain tooling and applicators for major connector families (TE, Molex, JST, Amphenol, Binder, Harting, LEMO, etc.), mirroring competitor capabilities with stocked terminals and applicators for consistency.

Industries & use cases

Industrial automation and robotics; medical & lab devices; aerospace/defense (Class 3); transportation & e-mobility (HV/BMS); electronics/ICT (USB-C, HDMI, LVDS, Ethernet). Assemblies are tailored for vibration, ingress, temperature, and EMC constraints of each domain.

Engagement flow

1. Send the package: drawing + netlist/pinout, connector PNs, environment/IP rating, quantities, and required IPC class.

2. DFM & quote: risks, alternates, and standard vs. expedite lanes.

3. Pilot & sign-off: first article, golden sample, test plan.

4. Supply: call-offs/Kanban, labeling/serialization, change control.

RFQ checklist (keep it tight) {#rfq}

• Drawing + netlist/pinout and connector part numbers

• Electrical limits (V/A), signal type, EMC/shielding, bend radius, IP target

• Tests required (continuity, HiPot/IR, functional), IPC class (A-620 1/2/3)

• Quantities & releases (prototype → batches/EAU) and delivery terms

• Compliance needs (UL AWM, RoHS/REACH, EN 10204 3.1, UDI/labeling)
