EMS Value-Added Service

What Are EMS Value-Added Services? (And Why They Matter)

EMS Value-Added Services are the difference between receiving a bare circuit board and receiving a finished, ready-to-ship product. They include every manufacturing step beyond standard SMT and THT assembly – prototyping, mechanical integration, wiring, and final packaging.

UNIXPLORE has provided these services from Dongguan, China since 2011. The goal is simple: reduce your vendor count from five to one.

The Three Core Problems That Value-Added Services Solve

Why Separate Vendors Increase Risk

Every additional vendor adds shipping, handling, quality variation, and communication delays. UNIXPLORE bundles these services so one quality system governs everything from bare PCB to sealed carton.

UNIXPLORE’s Three Core EMS Value-Added Services

UNIXPLORE focuses on three high-impact services that deliver measurable cost and time savings.

3D Printing Prototype Service

The best method to approve enclosure design at low cost is to 3D print in a couple of days.

Why this matters: Cutting a plastic injection mold costs 3,000 to 15,000. Finding a fit issue after mold cut adds weeks and thousands in rework. UNIXPLORE 3D prints your enclosure design using SLA or FDM printers before any steel is cut.

What UNIXPLORE provides:

• Printing within 2-3 business days of receiving STEP or STL files
• Materials: ABS-like, PLA, nylon, or resin (transparent for fit checks)
• Tolerances: ±0.2mm – sufficient for PCB mounting bosses, screw posts, and cutouts
• Up to 5 iterations included before mold approval

Cost: 50−300 per prototype depending on size and material – a fraction of mold rework.

Box Building and Finished Product Assembly

All-in-one factory service intended to save time and cost for customers.

What this includes: UNIXPLORE takes your PCBA, enclosure, display, battery, labels, and packaging – then delivers a sealed product ready for retail or distribution.

Step-by-step box build process at UNIXPLORE:

1. Sub-assembly – Mount PCBA into enclosure using correct screw torque.
2. Panel integration – Install displays, keypads, LEDs into enclosure cutouts.
3. Cable routing – Dress internal wires to prevent pinching or chafing.
4. Closure – Ultrasonic welding or screw assembly per your spec.
5. Labeling – Apply serial numbers, regulatory marks, or branding.
6. Packaging – Insert into inner tray, outer carton, apply shipping labels.

Certification advantage: Because UNIXPLORE handles the entire box build under one ISO9001:2015 certified roof, quality traceability is linear – not spread across three suppliers.

Wire Harness and Cable Assembly

UNIXPLORE is well-trained to provide this service for customers.

Faulty wiring is the #1 cause of intermittent field failures. Loose connectors, under-crimped terminals, and missing strain relief cause problems that pass factory testing but fail after 100 hours of customer use.

UNIXPLORE’s cable assembly capabilities:

Quality checks applied to every harness:

· Pull testing on crimped terminals (minimum 5 lb retention)

· Continuity testing on all conductors

· Dielectric withstand test for power cables

· Visual inspection for bent pins or damaged insulation

How Value-Added Services Reduce Your Total Cost

Many customers assume bundling services increases price. The opposite is true with UNIXPLORE.

Cost Comparison – Separate Vendors vs. UNIXPLORE One-Stop

Hidden Savings From UNIXPLORE Integration

1. No transit damage – PCBA moves directly to box build without external shipping.
2. One quality audit – Certifications (ISO9001, SGS, RoHS, UL) cover all services.
3. Single purchase order – Accounts payable processes one invoice, not four.

UNIXPLORE EMS Value-Added Service FAQ

These three questions are asked by every engineering team evaluating UNIXPLORE for full-service manufacturing.

Question 1: How does UNIXPLORE’s 3D printing prototype service work with the final box building – do you print the prototype and then build the production version using injection molding?

Answer: Yes. UNIXPLORE uses 3D printing strictly as a validation tool, not as a production method. The workflow is: first, UNIXPLORE receives your enclosure STEP file. Second, the engineering team prints a prototype within 2-3 business days using SLA resin or FDM filament. Third, you receive the printed enclosure (shipped or video-inspected) to test PCB fit, button travel, connector access, and screw alignment. Fourth, UNIXPLORE incorporates your feedback into a revised file. Fifth, after approval, UNIXPLORE sources or recommends an injection molding vendor for production quantities (typically 500+ units). The 3D printed unit is never used for final box building – it is only for design verification. UNIXPLORE does not perform in-house injection molding, but manages the mold maker and runs box build once molded parts arrive. Customers who skip the 3D printing step and go directly to mold cut face a 70% risk of requiring at least one mold modification (1,200−1,200−4,000 per change). UNIXPLORE includes two prototype iterations free with any box building contract over 1,000 units.

Question 2: Can UNIXPLORE perform box building and finished product assembly without having the PCBA made by UNIXPLORE – for example, if I already have assembled boards from another supplier?

Answer: Yes. UNIXPLORE accepts customer-supplied PCBAs for box building and finished product assembly. This is a common scenario for companies with an established PCBA vendor but no internal mechanical assembly capability. UNIXPLORE performs incoming inspection on your boards before box build, checking for dimensional compliance, connector alignment, and any damage from previous handling. A written report is provided. If UNIXPLORE finds defects (solder bridges, missing components, backward diodes), you are notified before any assembly work begins. The customer assumes responsibility for PCBA quality, while UNIXPLORE assumes responsibility for enclosure loading, screw torquing, cable dressing, and final packaging. Pricing for box-build-only is typically 15-20% higher than when UNIXPLORE also provides the PCBA, because the production line must pause for incoming inspection and handling of customer-owned material. Minimum quantity for customer-supplied PCBA box build is 250 units. All UNIXPLORE certifications (ISO9001, SGS, RoHS, UL) apply to the box building process even when the PCBA comes from another source – but UL recognition for the final product may require additional steps.

Question 3: What wire harness and cable assembly documentation does UNIXPLORE require, and what lead time should I expect for custom harnesses?

Answer: UNIXPLORE requires three documents for any custom wire harness: a wiring table (pin A connects to pin 1, pin B connects to pin 2, etc.), a cut length for each wire or overall harness length, and a connector specification (manufacturer and part number for each housing, terminal, and seal). A simple hand-drawn sketch is acceptable for prototypes. For production quantities, UNIXPLORE recommends a formal harness drawing with a bill of materials. Lead times: for prototype quantities (10-50 harnesses), UNIXPLORE ships in 5-7 business days using manual crimping and assembly. For production quantities (100-1,000 harnesses), lead time is 10-12 business days after UNIXPLORE receives all connectors and wire stock. For high-volume (5,000+ harnesses) requiring custom overmolding or automated cutting and stripping, lead time is 18-20 business days because tooling (crimping applicators, overmold fixtures) must be fabricated. UNIXPLORE stocks common wire types (UL1007 22AWG, UL2468 26AWG ribbon) and common connectors (JST XH, Molex KK, Dupont) for immediate turnaround. Unusual connectors (M12 circular, automotive sealed, high-current Anderson) must be customer-supplied or quoted separately with purchasing lead time added.

Quality Certifications Across All Value-Added Services

Many EMS providers certify only PCBA assembly. UNIXPLORE applies the same certifications to prototyping, box building, and harness assembly.

What ISO9001:2015 Means for Box Building

• Screw torque specifications are documented and audited
• Label placement accuracy is measured (tolerance ±0.5mm)

What RoHS Means for Wire Harnesses

• No lead in solder (if soldered connections are used)
• No cadmium in connector plating
