Question 2

Where is your factory located?

Accepted Answer

Our plant is in Bao'an District, Shenzhen, Guangdong, China — the global hub for precision electronics. It takes about 30 minutes to reach Shenzhen International Airport, and both Shenzhen and Hong Kong ports are close by, so worldwide dispatch is fast. You are welcome to visit in person, or we can set up a live video walk-through via WhatsApp or Zoom.

Question 3

Can you tell me about your company?

Accepted Answer

Shenzhen Hongyian Electronics Co., Ltd. is a national high-tech manufacturer founded in 2012. We run a 2,300 sqm facility with 200+ employees, including 8+ senior tooling engineers and 15+ QA/QC specialists. Our portfolio spans Board-to-Board, Wire-to-Board and Wire-to-Wire interconnects for industrial automation, clean energy, medical, automotive and telecom. In-house mold fabrication plus 95%+ automation lets us combine small-batch flexibility with 8-day turnaround on standard items.

Question 4

What industries use your products?

Accepted Answer

Three core sectors. Industrial automation is the biggest at around 60% — PLCs, servo drives, robot joints, CNC machinery, sensor networks, HMI panels. Renewable energy and storage run about 20% — solar inverters, BMS boards, EV charging modules, portable power cabinets. The rest covers telecom and consumer hardware: switches, routers, smart home devices, LED display backplanes and medical monitors.

Question 5

What types of connectors do you manufacture?

Accepted Answer

Ten major series and over 1,000 active specifications: Pin Headers (0.8–2.54mm pitch), Female Headers, Box & Ejector Headers, DIN41612 Eurocard connectors, machined round pin connectors, IDC sockets and flat ribbon cable assemblies, PCB Terminal Blocks (screw, spring, pluggable), D-Sub / SCSI / RJ45 I/O interfaces, M8/M12 waterproof circular connectors, FPC/FFC connectors, battery holders and contacts, plus fully custom wire harnesses.

Question 6

Do you offer custom connector manufacturing (OEM/ODM)?

Accepted Answer

Yes — OEM/ODM is our core strength. Eight senior tooling engineers and an in-house mold shop handle the full cycle: DFM review, tooling design, 3D printed prototypes, mass production. Custom pitch, pin count, plating, insulator height, housing color and wire gauge are all within our wheelhouse. Standard catalog MOQ is 100 pcs; custom runs start at 50–100 pcs. DFM feedback comes back in 2–4 hours, custom samples in 1–2 days, new molds in 7–10 days.

Question 7

Can you make connectors based on our drawings or samples?

Accepted Answer

Absolutely. Send a 2D drawing (DWG, DXF, PDF) or 3D model (STEP, IGES, SolidWorks), or even a physical sample. Our engineering team returns a full DFM review with technical optimization within 2–4 hours. Functional 3D-printed prototypes follow in 24–48 hours for mechanical verification, and custom molds are built in-house in 7–10 days. We also accept form-fit-function equivalents — if you name a big-brand part number, we can reverse-engineer a drop-in replacement.

Question 8

What are your best-selling products?

Accepted Answer

Four high-volume categories: standard 2.54mm / 2.0mm / 1.27mm gold-plated pin headers and female sockets (industrial control boards, embedded systems); 1.27mm and 2.54mm IDC flat ribbon cable assemblies (signal buses, LED panels); high-temperature PCB terminal blocks in pluggable and spring-clamp types (power supplies); and JST/Molex-compatible custom wire harnesses for automation and clean-energy BMS systems.

Question 9

What's new in your product line?

Accepted Answer

Recent additions: ultra-fine pitch 0.8mm and 1.0mm dual-row SMT pin headers and sockets for compact IoT and wearable boards; heavy-duty high-current battery and BMS wire harnesses with high-temperature insulation for solar storage and EV charging; IP68 overmolded M8/M12 circular connectors with A/B/D coding; and LCP 260°C lead-free reflow headers for demanding SMT profiles. Ask us for the 2026 new product brief.

Question 10

What certifications does Hong YiAn hold?

Accepted Answer

The factory runs under ISO 9001:2015. All products comply with EU RoHS 2.0 (Directive 2011/65/EU) and REACH (EC 1907/2006), verified by third-party SGS test reports. Plastic resins (PA66, LCP, PBT) carry UL94V-0 flammability ratings and meet halogen-free high-temperature reflow standards. We provide high-resolution ISO certificates, SGS reports and Certificates of Analysis for your engineering files.

Question 11

How do you control product quality?

Accepted Answer

A strict four-stage workflow under ISO 9001:2015. IQC checks incoming materials — copper conductivity, spring elasticity, plating thickness, plastic flammability. IPQC runs hourly first-article inspections, molding burr audits and pin pull-force tests. FQC applies 100% automated CCD optical inspection for pin straightness and coplanarity (≤0.1mm) plus dielectric withstanding voltage tests. OQC handles pre-shipment audits and issues a Certificate of Analysis with every batch.

Question 12

Do you have third-party factory audit reports?

Accepted Answer

Yes. Official third-party audit reports verified by world-leading inspection agencies such as SGS and TÜV Rheinland cover our manufacturing facility, production machinery, daily capacity, headcount, QA testing equipment and export credentials. We can send the full PDF, and we welcome physical third-party audits or live video walk-throughs of the production floor.

Question 13

What is your warranty policy?

Accepted Answer

Every connector, terminal block and cable assembly carries a 12-month quality warranty. If any dimensional, solderability or electrical defect appears within 30 days of receipt, our engineering team responds within 12 hours. Confirmed factory defects get 100% free expedited replacement or refund — shipping on us. For qualified industrial and infrastructure projects, extended warranties up to 2–3 years are available with thicker gold plating and full batch material test data.

Question 14

What is your minimum order quantity (MOQ)?

Accepted Answer

Standard catalog connectors — pin headers, female sockets, box headers, terminal blocks — start at just 100 pieces. Custom connectors and wire harnesses start at 50–100 pieces depending on wire gauge and complexity. Unlike big brands that demand tens of thousands, we keep the door open for engineering prototypes and pilot runs.

Question 15

Do you offer free samples?

Accepted Answer

Yes. Two to ten pieces of standard catalog connectors are free — you cover courier freight or give us your DHL/FedEx/UPS account. For custom tooled parts or specialized harness prototypes with a nominal setup fee, that fee is 100% credited against your first bulk order, so evaluation costs you nothing beyond shipping.

Question 16

What is your production lead time?

Accepted Answer

Standard catalog connectors ship in 8 business days. Custom dimensions (special pin length, insulator height) take 8–10 business days; custom cable harnesses run 10–12 business days. New custom tooling delivers first articles in 7–10 days. For genuine line-down emergencies, our fast-track channel dispatches an initial batch in 3–5 business days.

Question 17

Can I mix different products in one order?

Accepted Answer

Absolutely. Mix pitches, pin counts, SMT and DIP headers, terminal blocks and custom ribbon cables in a single order — we consolidate everything into one shipment. Since every core product line is made in-house, we synchronize production schedules and pack into a single pallet or master carton for denser packing and lower freight.

Question 18

What are your price terms (Incoterms)?

Accepted Answer

Full Incoterms 2020 coverage. EXW from our Shenzhen factory if you have your own forwarder. FOB Shenzhen or Hong Kong with domestic trucking and export docs handled. CIF/CFR when you want us to book ocean or air freight. DAP and DDP are the most popular — international freight, customs clearance and import duties all prepaid, delivered to your door.

Question 19

What payment methods do you accept?

Accepted Answer

Wire transfer (T/T) is standard: 50% deposit to lock raw material prices and start production, 50% balance before dispatch after inspection approval. We also accept irrevocable L/C at sight for large contracts, PayPal and major credit cards. For established clients with a stable order history, open account terms (Net 30/60) can be arranged after credit review.

Question 20

Why are your prices higher than some trading companies?

Accepted Answer

Because we refuse to cut the corners they cut. Ultra-low quotes often mean recycled iron pins instead of copper, flash plating without nickel underplate, or recycled plastic that blisters at 260°C reflow. We use virgin PA66/LCP with UL94V-0 rating, phosphor bronze with 50U' nickel barrier and real gold plating tested to 24–48h salt spray. The result: 99.98%+ SMT yield and no warranty surprises. Against big brands, we are still 30–50% cheaper.

Question 21

Do you offer discounts for distributors and resellers?

Accepted Answer

Yes. Tier-1 wholesale pricing leaves 20–35% margin headroom versus regional distributor catalogs. Annual blanket orders earn quarterly or annual rebates. We hold agreed semi-finished buffers in our Shenzhen warehouse for call-off dispatch. Value-engineering — like selective gold on contacts with pure tin on solder tails — cuts unit cost 15–25% without touching electrical performance. Neutral OEM packaging and blind drop-shipping are available for resellers.

Question 22

Do prices include customs duties at my end?

Accepted Answer

EXW, FOB and CIF quotes exclude destination import duties, VAT/GST and port handling — those are the importer's responsibility. If you want one all-in number with nothing extra at delivery, ask for a DDP quotation: we cover freight, clearance and all import tariffs for North America, Europe and Southeast Asia.

Question 23

What shipping options do you offer?

Accepted Answer

International priority express (DHL, FedEx, UPS, TNT) reaches North America, Europe and Asia in 3–5 business days. Dedicated air freight lines take 5–7 days door-to-door. For bulk, ocean LCL or DDP sea freight cuts freight cost up to 70%. Rule of thumb: under 15kg express wins; 20–100kg dedicated air saves 30–50%; over 100kg sea is the smart play. Share your postal code and volume and we'll price three options side by side.

Question 24

Can you ship door-to-door with customs clearance included?

Accepted Answer

Yes. Express door-to-door via DHL/FedEx/UPS for parcels; DDP (Delivered Duty Paid) door-to-door for any volume — we handle export customs, international transit, import clearance and all duties and taxes. Goods arrive at your office, warehouse or EMS line with zero paperwork on your side. If you ship via DDP or express, you don't even need a customs broker.

Question 25

How do I place an order?

Accepted Answer

Five steps. Confirm specs or send your drawing (pitch, pin count, plating, packaging). We issue a formal Proforma Invoice with tiered pricing. You arrange payment by T/T, L/C, PayPal or credit card. Production runs with 100% automated inspection. Goods ship on your chosen carrier with tracking sent the day of dispatch.

Question 26

Do you have a product catalog and 3D CAD models?

Accepted Answer

Yes. Our 2026 digital catalog (PDF) covers every series — Pin Headers, Female Sockets, Box & Ejector Headers, DIN41612, IDC Ribbon Cables, Terminal Blocks, RJ45/D-Sub/SCSI interfaces, M8/M12 waterproof connectors and custom harnesses. A full 3D CAD/STEP model library is ready for Altium Designer, KiCad and Eagle. Browse our website product pages, or email us your target series and we'll send the download package.

Question 27

Can we become your exclusive distributor?

Accepted Answer

We welcome the conversation. Exclusive distributorship is evaluated on agreed purchasing turnover targets, proven local sales channels and technical support capability in your target industry, and brand promotion commitments. Typical structure: a 3–6 month trial period to validate market demand, then a formal regional exclusive agreement with territorial protection and lead referrals.
