Product Summary
PCB-999 / PCBA-999 is a 4-layer FR-4 board produced for turnkey PCB assembly. The construction uses 1 oz copper on a 1.2 mm board, green solder mask, white silkscreen and a HASL lead-free surface finish, with 3 mil minimum line width and spacing and a 0.2 mm minimum hole. Jerico assembles SMT and DIP components, then verifies each order with fixture E-test or fly-probe E-test according to order quantity. Finished boards ship vacuum packed.
Key Features
4-Layer FR-4 Construction
1 oz copper on a 1.2 mm FR-4 board gives a stable platform for power-related circuits and mixed-signal routing.
Fact: 4 layers, 1 oz copper, 1.2 mm boardHASL Lead-Free Finish
A lead-free HASL surface supports reliable solderability for volume PCBA assembly and reflow soldering.
Fact: HASL lead-free surface finishingFine Feature Control
3 mil minimum line width and spacing with a 0.2 mm minimum hole supports dense routing and small through-holes.

Orders start at 1 pc, so the same specification can be used from first prototype through volume production.
Fact: MOQ 1 pc, vacuum packageModels and Options
PCB-999 Bare Board
4-layer FR-4, 1 oz copper, 1.2 mm thickness, HASL lead-free finish, green mask and white silkscreen.
PCBA-999 Turnkey Assembly
Board fabrication plus SMD, SMT and DIP component assembly under one order.
Electrical Test Options
Fixture E-test or fly-probe E-test, selected according to order quantity.
Order Quantity
MOQ 1 pc for prototypes, with vacuum packing for shipment.
Materials and Structure
The board is built on FR-4 laminate with a 4-layer stack, 1 oz copper and a 1.2 mm finished thickness. Green solder mask and white silkscreen are standard, and the exposed copper is finished with lead-free HASL. Minimum line width and spacing are both 3 mil, and the minimum drilled hole is 0.2 mm. The same construction is used for both bare board supply and turnkey assembly.
Applications
- Consumer electronics
- Industrial control and automation
- Security and surveillance
- Telecommunication and networking
- Automotive electronics
- Medical equipment
- IoT and smart home
Customization
Board thickness is customizable around the 1.2 mm standard, and assembly scope is quoted from the customer BOM and drawing. Test method is chosen by order quantity: fixture E-test for larger runs, fly-probe E-test where quantity or design calls for it. The same factory also produces 1-18 layer rigid boards, HDI with blind and buried vias, heavy copper, high-frequency and metal-core boards, and offers ENIG, ENEPIG, OSP, immersion tin and immersion silver finishes alongside HASL.
