For hardware teams, the step from a working schematic to a finished board is the step that usually slips. Haiben, founded in Shenzhen in 2013 and exporting since 2015, offers a PCBA service that takes customer design files through BOM analysis, component sourcing and manufacturing to testing, finished-product assembly and delivery. The company also stocks and supplies its own-brand component sourcing lines, including the Weforsemi line of crystals and crystal oscillators, alongside a broad range of discrete semiconductors, ICs and modules — so purchasers and engineers can plan a pcb assembly project and its bill of materials in one place.

PCBA with the components already attached — commercially

The commercial side of pcb assembly is often where internal debates stall. Haiben's published platform terms are straightforward: no MOQ for standard parts, and samples are available, with most standard parts free (freight paid by the buyer and credited against the first order). Average lead time is stated as within 15 workdays in both peak and off-peak seasons, and every order carries a 12-month warranty. Payment is accepted by L/C, T/T, D/P, PayPal and Western Union, with Incoterms FOB, EXW, CFR, CIF and DDP; the nearest ports are Shenzhen, Guangzhou and Dongguan. With export experience since 2015 across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, Eastern Asia and Western Europe, these are terms a purchasing team can schedule and finance against rather than exceptions to negotiate case by case.

The assembly workflow, stage by stage

The company's published PCBA workflow is a single sequence, and it is worth reading as a checklist of where information changes hands:

Quality control runs alongside that sequence as a three-stage inspection: incoming inspection, in-process testing and final delivery inspection, stated by the company as full inspection. The team behind it is company-stated at 35 senior R&D engineers and 6 quality engineers — a useful figure when judging how much engineering support a supplier can put behind pcb assembly rather than simply quoting it.

Prototype, small batch and volume runs

The PCB & PCBA Solutions line covers custom PCB design, PCBA manufacturing and module assembly for prototypes, small batches and volume production. At the prototype end, free samples help confirm that footprint, orientation and programming work before a pilot run. In the middle, the no-MOQ policy for standard parts means a small batch is not penalised for being small. At volume, the same BOM analysis and cross-reference work done early carries through, provided component choices are agreed before tooling. For boards that include serial flash, one stocked anchor is the BL25Q128G — a 128 Mbit serial (SPI) NOR flash memory IC in an SOP-8 208 mil package, operating from 2.3 V to 3.6 V, per the manufacturer's published listing data. Note that this is data quoted from that listing; it is not a Haiben test report.

Sending a PCBA project: files and information

A pcb assembly quote is only as good as the package behind it. Bring the complete BOM with manufacturer part numbers and acceptable alternates, the Gerber set, pick-and-place data, and assembly drawings showing polarity and connectors. State the target quantity and whether the run is prototype, small batch or volume. Add test requirements and any programming files, plus the packaging and labelling your warehouse needs. BOM kitting fits naturally at this stage: supplying the full kit — including connectors, capacitors, resistors and inductors listed among the handled parts — reduces split sourcing. Crystal requirements are worth confirming explicitly, since none are published as standard SKUs. Buyers typically specify frequency, load capacitance, tolerance and stability in ppm, and package format such as SMD crystals; common values include 32.768 kHz watch crystals and MHz-range points such as 8, 12, 16, 24, 25 and 40 MHz. Treat these as requirements to state in your brief. If a design includes an offline speech function, see voice modules for the related line.

Frequently asked questions

Does Haiben hold distribution authorisation for the third-party parts it sources?

No such claim is made. The company is an electronic components supplier in Shenzhen with its own Weforsemi line, operated by its wholly-owned subsidiary, and its stated role is component sourcing with cross-reference equivalents as part of the service flow.

Can I send a project for prototypes before committing to a volume order?

Yes. The PCB & PCBA Solutions line is structured for prototypes, small batches and volume production, and standard parts carry no MOQ, so a first run can be sized to what you need to prove the design.

How long does a PCBA project usually take?

The published commercial terms state an average lead time within 15 workdays in peak and off-peak seasons. Actual timing depends on the completeness of your BOM and files and on component availability during sourcing.

Send your part numbers or BOM

Send the part numbers you are buying — or the full BOM — and the team replies with stock, cross-reference options and pricing. Most standard parts carry no MOQ, and samples are available.
