02 / BOARD TECHNOLOGIES
## The right structure. The details that matter.
[All PCB technologies ↗](https://www.chinasuqi.com/en/pcb-technologies/)
technology
### [Rigid PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/rigid/)
Rigid boards provide a fixed mechanical platform for circuit interconnections. Define board thickness, copper distribution, drilled features and outline tolerances as part of the manufacturing package.
technology
### [HDI PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/hdi/)
HDI fabrication supports high-density interconnections using fine circuit features and defined via structures. The buildup sequence and layer spans are essential manufacturing inputs.
technology
### [Flexible PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/flexible/)
Flexible circuits connect electrical requirements with a bendable structure. Define the flex material, construction, coverlay and any local reinforcement needed by the design.
technology
### [Rigid-flex PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/rigid-flex/)
Rigid-flex boards integrate rigid sections with flexible interconnections. Fabrication requires a clear definition of each region and how the layer structure transitions between them.
technology
### [Metal-core PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/metal-core/)
Metal-core PCB construction combines circuit layers with a metal base and an insulating system. Define the thermal, electrical and mechanical requirements together.
technology
### [Heavy-copper PCB fabrication ↗](https://www.chinasuqi.com/en/pcb-technologies/heavy-copper/)
Heavy-copper designs require copper thickness, circuit geometry and thermal requirements to be reviewed together. State the finished copper requirements separately for inner and outer layers.
03 / ENGINEERING FIRST
## Review the whole board. Not just a minimum value.
Stackup, material, copper and feature geometry work together. Match the manufacturing route to your actual requirements.
[Check manufacturing requirements ↗](https://www.chinasuqi.com/en/capabilities/)
01
### Construction & stackup
Layer arrangement, thickness and via structure.
02
### Materials & copper
Specified grades, inner and outer copper.
03
### Features & verification
Holes, tolerances, finish and acceptance criteria.

04 / MANUFACTURING & QUALITY
## Quality starts before the board is made.
Engineering confirmation, material checks, process control and final verification connect the approved requirements to the finished boards.

Questions, answered
## Before your next build
Do you manufacture bare boards or assembled electronics?
PCBELEC offers PCB fabrication and PCB assembly (PCBA). Specify whether you need bare boards, assembly, or both so the quotation covers the correct files, materials and verification requirements.
What information is needed for a PCB quote?
Start with fabrication artwork, drill files, a drawing or written specification, quantity and a required date. Add stackup, materials, copper, finish and test requirements.
How do I choose between rigid, HDI, flex and metal-core PCBs?
Start with the design requirement: routing density, mechanical flexibility, RF behavior or thermal integration. Then review the complete construction rather than selecting by a single headline parameter.
