Professional PCB Manufacturer 94V0 High Frequency PCB Board

♦ What's 94V0?

94V-0 is the highest vertical-burn classification in the UL 94 plastics-flammability standard.
A material rated UL 94V-0 must:

• Self-extinguish within 10 s after each of two 10-second flame applications
• Show no flaming drips that ignite cotton placed below the sample
• Have a total after-flame time ≤ 50 s for all five test specimens
• Exhibit no burn-through to the holding clamp

In the PCB world, a “94V-0 board” simply means the laminate (typically FR-4) has passed this test, giving the circuit board high fire resistance suitable for power, industrial, automotive, or consumer products that must meet strict safety codes.

♦ ​​Key Features of PCB Manufacturing Service:

​​

• Design Submission​​

Customers provide design files (usually in ​​Gerber format​​, along with drill files, BOM, and assembly drawings).

Engineers review the design for manufacturability (DFM checks).

• ​​PCB Fabrication Process​​

​​Material Selection​​ – Choosing substrate materials (e.g., FR-4, Rogers, flexible PCBs).

​​Printing & Etching​​ – Transferring the circuit pattern onto copper-clad laminate.

​​Layering & Lamination​​ (for multi-layer PCBs).

​​Drilling & Plating​​ – Creating vias and through-holes.

​​Solder Mask & Silkscreen​​ – Applying protective coating and component labels.

​​Surface Finish​​ – Options like HASL, ENIG, OSP, or immersion silver/gold.

​​Electrical Testing & Inspection​​ – Ensuring no shorts or open circuits (e.g., flying probe test, AOI).

• ​​Additional Services (Optional)​​

​​PCB Assembly (PCBA)​​ – Soldering components onto the board (SMT or through-hole).

​​Testing & Quality Control​​ – Functional testing, burn-in testing, etc.

​​Box Build & Packaging​​ – Full product assembly.
