Guides go deeper than blog posts, such as our cable harness manufacturing guides. Where the blog covers shorter timely content, guides are evergreen reference material — meant to be read once and referenced repeatedly. We organize them across five learning paths covering different audiences and depths. Whether you’re specifying your first custom cable, choosing between PVC and silicone for an outdoor IoT product, or preparing for an IATF 16949 audit, the guides below give you a starting point. Each guide links into the relevant product and compliance pages for deeper detail. New guides published as topics emerge from customer questions and engineering reviews.

Getting Started

Foundational guides for buyers and engineers new to cable assembly procurement. Targets the first-time custom-product buyer, the cross-functional product manager, and the startup founder building hardware. No assumed industry experience.

  • How to specify a custom cable assembly — what the spec sheet should contain, what to leave for supplier discretion, common mistakes that cause delays.
  • Cable vs harness vs flex circuit: terminology guide — when each term applies, what makes a cable assembly different from a wire harness, when FFC or FPC fits better. See our cable assembly and wire harness overview pages.
  • Choosing the right connector for your application — voltage, current, environmental, mating cycle, and cost factors that drive connector selection.
  • First-time buyer’s guide to working with Chinese cable manufacturers — RFQ etiquette, sample workflow, payment terms, IP protection, what to inspect during factory visits.

Material Selection

Material decisions drive both performance and cost. Wrong material choice early in design causes either over-engineering (wasted cost) or under-engineering (field failure). These guides walk through the trade-offs.

  • Insulation material guide: PVC vs Silicone vs PTFE vs FEP vs TPU — temperature, flexibility, chemical resistance, cost, and certification implications for each.
  • Conductor material selection: bare copper vs tinned vs silver-plated vs gold-plated — when each plating matters, salt spray and oxidation considerations, cost premium per option.
  • Connector body material guide: nylon vs glass-filled nylon vs LCP vs PEEK — temperature ratings, flame ratings, autoclave compatibility, dimensional stability under stress.
  • Outdoor cable jacket UV stability comparison — xenon-arc test methods, polyurethane and TPE stabilizer chemistry, hydrolysis resistance for 10-20 year outdoor service life.
  • Shielding selection: foil vs braid vs spiral vs combination — frequency coverage, flex life, termination methods, EMI/EMC implications.

Compliance and Standards

Quality systems and product standards are where most first-time medical, automotive, or aerospace programs run into trouble. These guides explain the standards from a supplier’s perspective — what your cable manufacturer needs to know to support your program.

  • IPC/WHMA-A-620 complete guide: Class 1, 2, 3 explained — full breakdown of acceptance criteria, when each class applies, how to specify the right class without over-paying. See our IPC/WHMA-A-620 page for the foundational framework.
  • ISO 13485 medical device QMS for cable suppliers — DHR requirements, design controls, risk management, what auditors look for. See our medical solutions page for industry context.
  • IATF 16949 first-time supplier playbook — PPAP submission, AEC-Q200 component sourcing, control plans, capability studies, audit preparation.
  • EU MDR 2017/745 transition guide for medical cable — what changed from MDD, technical documentation requirements, post-market surveillance, UDI marking.
  • AS9100 aerospace quality system primer — how AS9100 builds on ISO 9001, configuration management, traceability, and special process controls.

Manufacturing Process

Process guides for engineers who want to understand what happens inside the factory. These cover the actual operations — how a cable goes from raw materials to packaged finished good.

  • Crimping fundamentals: pull force, gas-tight, micrograph cross-section — what makes a good crimp, common defects (under-crimp, over-crimp, wire whisker), inspection methods.
  • Overmolding process selection: insert vs 2-shot vs RIM — when each process fits, tooling cost trade-offs, material compatibility considerations. See our overmolded cable page.
  • EOL testing methods: continuity, hi-pot, insulation resistance, functional — what each test detects, when each is required, test fixture design considerations.
  • Soldering process guide: hand vs solder pot vs wave — when each process applies, defect modes, J-STD-001 compliance.
  • Wire preparation and stripping techniques — automatic vs semi-automatic vs hand stripping, tolerance ranges, common errors that show up later in production.

Industry-Specific Design

Design checklists and considerations specific to high-stakes industry applications. These bridge the gap between general design principles and industry-specific requirements.

  • EV charging inlet design checklist (CCS1 / CCS2 / GB-T / NACS) — connector standards, thermal monitoring, HVIL integration, regional certification. See our battery harness page.
  • 5G base station RF cable considerations: FAKRA, mini-FAKRA, 4.3-10 — frequency-specific connector selection, insertion loss budget, phase matching for MIMO, weather sealing for outdoor RRU/AAU installations.
  • Medical reusable instrument cable design (autoclave 135 °C) — silicone vs PEEK construction, connector materials that survive thousands of sterilization cycles, biocompatibility documentation.
  • Industrial robot drag chain cable selection (5M / 10M / 20M+ cycles) — flex life rating, bend radius minimums, torsion considerations for robotic J5-J6 axes.
  • IoT outdoor enclosure cable entry sealing (IP67 / IP68 / IP69K) — gland selection, strain relief, ingress protection testing, salt spray considerations for coastal deployments.
  • Aerospace harness design under MIL-STD-1553 and DO-160 — twisted-shielded-pair construction, 1553 protocol implications, environmental qualification for avionics.

How to Use These Guides

Three suggested paths through the guide library:

  1. If you’re starting a new program from scratch — Getting Started → Material Selection → Industry-Specific Design (for your sector) → Compliance and Standards (for your sector). This sequence covers product definition through quality system in roughly the order decisions need to happen.
  2. If you have a specific design problem — jump straight to the relevant Material Selection or Manufacturing Process guide. These cross-reference each other so you’ll find adjacent topics quickly.
  3. If you’re preparing for an audit — Compliance and Standards section is the priority. Each compliance guide is structured around what auditors actually verify rather than abstract standard text.
