PCB & semiconductors
Part of the Electrical & Electronic Equipment sector
PCBs and semiconductors are the foundation of electronic hardware — the boards that carry circuits and the chips that run them. This hub explains the main categories and how to find and compare verified suppliers on Digibition.

Overview
This sub-industry covers printed circuit boards and semiconductor devices. PCBs range from single and double-sided boards to multilayer, flexible and rigid-flex constructions, supplied as bare boards or as assembled boards (PCBA). Semiconductors span discrete devices such as diodes and transistors, logic and analog chips, microcontrollers and processors, memory, and power devices.
Products are defined by their datasheet and by process parameters: for PCBs, the layer count, material, finish, track and spacing tolerances; for semiconductors, the part number, package, grade and lifecycle status. Buyers include product designers, contract manufacturers (EMS), OEMs and distributors.
On Digibition, PCB fabricators, assembly houses, semiconductor manufacturers and authorised distributors publish verified profiles, so professional buyers can discover and compare them by specialization and country.
What to check when sourcing
When you source PCBs and semiconductors, the fundamentals are authenticity, an exact match to your design or datasheet, and continuity of supply. For semiconductors in particular, counterfeit and relabelled parts are a real risk, so prefer manufacturers and authorised distributors and ask about traceability, lot codes and lifecycle status.
For PCBs, confirm the fabricator can meet your stack-up, materials, finish and tolerances, and clarify what files, testing and quality level are included. For semiconductors, verify the exact part number and package against the datasheet and check whether the part is active or heading toward end-of-life. Weigh lead times, which can be long, alongside minimum order quantities and packaging. This is general information, not legal or technical advice.
Use the directory to shortlist suppliers by specialization and country, then contact several and compare their responses before you commit.
What to check when sourcing PCBs and semiconductors
| Criterion | What to look for |
|---|---|
| Authenticity | Manufacturer or authorised distributor; traceable lot and date codes |
| Design match | PCB stack-up, material and finish, or exact semiconductor part and package |
| Tolerances & grade | Track and spacing tolerances, or the device grade for your use |
| Lifecycle | Active, versus not-recommended-for-new-design or end-of-life |
| Lead time & MOQ | Realistic lead times and minimum order quantities for your volume |
| Testing & quality | Included testing, inspection and the quality level agreed |
Frequently asked questions
- What is the difference between a bare PCB and a PCBA?
- A bare PCB is the board on its own, with the copper, layers and finish but no parts fitted. A PCBA (printed circuit board assembly) is a board with components soldered on. Sourcing a PCBA means the supplier also handles component placement and soldering.
- What do PCB layers and finish mean?
- Layer count is how many conductive layers the board has, from single-sided up to many-layer boards, and the finish is the surface treatment applied to pads for solderability and protection. Both must match your design, so confirm them against your fabrication files.
- How do I find PCB and semiconductor suppliers?
- Use the Digibition directory to filter by this specialization and by country, then open each company profile to review its products, certifications and specializations. You can message suppliers directly, or add several to a quote list and request quotes from all of them at once.
- How can I avoid counterfeit semiconductors?
- Prefer manufacturers and authorised distributors, ask for traceability and lot or date codes, and verify every part against the official datasheet. Be cautious with unusually low prices or hard-to-find parts. This is general information, not legal or technical advice.
- What should I check before placing a large order?
- Confirm the exact design match or part number and lifecycle status, agree tolerances, testing and quality level, and clarify lead time, minimum order quantity and packaging. Where possible, request a sample build and agree acceptance terms in writing before committing to volume.
