Smart Control PCBA Solution Provider & PCBA Manufacturer
We design and assemble custom control boards for heaters, air conditioners, fans, smart appliances and connected products. Send us your product requirements, existing board, schematic or Gerber files. Our team can support hardware design, firmware development, sourcing, PCBA assembly, programming and production.
What We Do: One Engineering, Sourcing & PCBA Partner,
From Design to Finished Product
We coordinate the electronics development and PCBA production
flow—from design and qualified bare PCB sourcing through SMT/THT
assembly, testing, NPI and volume production.
Each stage is managed under one project workflow. Bare PCBs are
sourced from qualified supply partners, while PCBA assembly and
project-defined validation are completed in-house. Flip a card to
see the operations.

Our Team: The Engineers and Systems Behind Every PCB Board & PCBA
Every HS board is built the way a true PCBA manufacturing partner should build it: by experienced engineers and a system measured against real production data.
The numbers below show our capacity, quality and delivery record, and the standards they are built on: ISO 9001 quality management and IPC J-STD-001 assembly requirements.

The essentials behind PCB boards and PCBA — what they are, how they differ, and how HS manufactures them from prototype to mass production.
What is a PCB?
A PCB (Printed Circuit Board) is the substrate that mechanically supports electronic components and provides electrical connections through conductive traces. A bare PCB is not, by itself, a finished electronic product.
What is a PCBA?
PCBA (Printed Circuit Board Assembly) is the board created by mounting and soldering electronic parts onto a bare PCB according to the design. The finished board includes the PCB, SMT components, through-hole (DIP) parts, firmware programming and functional testing.
What is the difference between a PCB and a PCBA?
A PCB is the bare board — the focus is substrate material, traces, plating, solder mask and surface finish. A PCBA is the PCB after component placement, insertion, soldering, inspection and required testing are complete.
What is the difference between PCB manufacturing and PCB assembly?
PCB manufacturing (fabrication) produces the bare board; PCB assembly mounts the components onto it. A complete electronics manufacturing service extends further into testing, programming, wiring harnesses, mechanical parts and box build.
What is EMS?
EMS (Electronics Manufacturing Services) is when a single partner handles multiple stages of electronics production — typically component sourcing, PCB assembly and testing, and often design and fabrication. HS acts as an EMS / PCBA manufacturer: design, PCB fabrication, SMT/DIP, test and delivery under one roof.
What is turnkey PCB assembly?
In a turnkey model the supplier manages the complete sourcing and manufacturing chain — bare boards, component procurement, PCB assembly and related production services — and delivers ready-to-use PCBAs. You provide the design files (Gerber, BOM, pick-and-place); HS handles the rest.
