Who buys from us

Built for whoever is holding the tool

A training school and a phone line buy from the same catalogue for completely different reasons. These are the four the range is built around.

How we work
  • Repair training schools at work

    Repair training schools

    Class sets of stencils, microscopes and stations, plus the firmware and blueprints the course teaches from.

    Optics and microscopes
  • Phone manufacturers at work

    Phone manufacturers

    Mid-layer test fixtures, interface testers and the production fixtures a line runs all day.

    Test fixtures and meters
  • Professional repairers at work

    Professional repairers

    Thermal cameras, BGA rework and the board-level instruments a component-repair bench is built on.

    Rework stations and power
  • New repairers at work

    New repairers

    A first hot-air and soldering setup, the hand tools that go with it, and consumables at a low minimum order.

    Consumables and starters

Eight areas of the bench, 26 product lines

Everything we make sits in one of these areas. Open one to see the whole line, including the voltage and plug variants that are usually buried in a price list.

All 1,050 part numbers

Why shops move the whole bill of materials to one supplier

We build the instruments, cut the stencils and stock the consumables. That matters most on the day something goes wrong with an order.

Manufacturing
Own factory
A 10,000 m² plant in Fenggang, Dongguan with in-house CNC, and a separate PCB assembly line for the instruments.
Engineering
100+ specialists
Industrial design, structure, hardware, firmware, software and supply chain sit in one team, so a fix to a stencil or a firmware bug does not cross a company boundary.
Range
1,050 part numbers
From a 17,000 RMB laser to a 4 RMB dust cloth — the whole bench from one supplier, one packing list, one invoice.
Markets
100+ countries
Voltage and plug variants for China, Europe and the US are held as separate part numbers, not adapters.
Quality
ISO 9001:2015
National high-tech enterprise, China Red Star Design Award 2020, and 300+ registered trademarks and patents.
Support
Bench-level help
Firmware, wiring diagrams and repair guides for every instrument we sell, plus a technical contact who has used the tool.

How an order works

No account, no minimum basket and no obligation to buy a container. Most first orders start as a sample of one instrument.

  1. 01

    Send the part numbers

    Add items to the quote list and send it, or email your own list. Chinese names are fine — we map them to part numbers for you.

  2. 02

    Get a priced offer

    We reply within one working day with unit price, minimum order, packing and lead time for each line.

  3. 03

    Sample if you want one

    Instruments can be shipped as a single sample before you commit to a container or an air shipment.

  4. 04

    Production and QC

    Consumables and stencils come from stock; instruments are built and tested to order with a burn-in check.

  5. 05

    Shipping and after-sales

    Express, air or sea with tracking, plus a 14-month warranty and spare parts for everything we manufacture.

Who we are

A workshop in Shenzhen that makes the tools it sells

杨长顺维修家 started on a bench in Huaqiangbei and now builds the instruments behind it — microscopes, hot-air and soldering stations, screen machines, mid-layer test fixtures, chip programmers and the reballing stencils a board-level job runs through. The people who design a tool here are the people who answer the phone about it.

Voltage and plug standard are separate part numbers in our catalogue, not accessories. Ordering the wrong one is the most common mistake in a first order, and the easiest to avoid.
