Our Electroless Nickel TG180 8 layer PCB board with BGA (Ball Grid Array) structure offers reduced package size, increased pin count, self-centering during soldering, excellent electrical performance, high reliability, and low overall cost. BGA PCBs typically feature numerous holes, with most customers specifying finished hole diameters of 8-12mil and BGA surface spacing of at least 10.5mil (standard 31.5mil). All BGA vias require hole plugging, with no ink allowed on BGA pads and no drilling permitted on BGA pads.
Multilayer PCB Production Process
- Design: Schematic and layout creation using specialized PCB design software, including layer stack-up definition, trace routing, component placement, and signal integrity considerations.
- CAM Processing: Conversion of design data into manufacturing instructions (Gerber files, drill files, layer-specific information).
- Material Preparation: Cutting core material (typically FR-4 fiberglass epoxy) to panel sizes and preparing copper foil sheets.
- Inner Layer Processing:
- Cleaning copper foil
- Laminating copper to core material
- Applying and exposing photoresist
- Etching unwanted copper
- Drilling precision holes
- Outer Layer Processing: Similar to inner layer processing with additional soldermask and silkscreen application.
- Multilayer Lamination: Stacking and bonding layers with prepreg material under heat and pressure.
- Plating and Surface Finish: Electroplating vias and applying protective surface finishes (tin, lead-free solder, or gold).
- Routing and V-Cut: Separating individual PCBs from panel.
- Assembly: Component placement and soldering.
- Testing and Inspection: AOI, functional testing, and quality checks.
- Packaging and Shipping: Final preparation for transportation.
Multilayer PCB Stack-Up
Our multilayer PCB stack-up configuration is carefully designed to optimize electrical performance, signal integrity, impedance control, and thermal characteristics. The standard arrangement includes:
- Signal Layers: Copper traces for electrical signals, sandwiched between power/ground planes
- Power and Ground Planes: Stable voltage references and return paths
- Prepreg Layers: Insulating material between signal layers
- Core Layer: Central FR-4 layer for mechanical stability
- Surface Layers: Outermost layers for component connectivity
- Soldermask and Silkscreen: Protective coating and component markings
Multilayer PCB Types
- Standard Multilayer PCB: 4-8 layers for general electronics
- HDI PCB: High density with microvias for compact devices
- Flex/Rigid-Flex PCB: Flexible sections for wearable/medical devices
- Sequential Lamination PCB: 10+ layers for complex designs
- Metal Core PCB: Aluminum/copper core for heat dissipation
- RF/Microwave PCB: Specialized for high-frequency applications
Applications
Our multilayer PCBs serve diverse industries including consumer electronics, telecommunications, automotive, industrial equipment, aerospace/defense, medical devices, power electronics, and industrial control systems.
