Custom Outline 2-Layer FR4 Rigid PCB with HASL Surface Finish, 1.6mm Thickness, White Solder Mask, Half-Ounce Copper Weight
For B2B buyers, R&D teams, and engineers sourcing a practical yet customizable board, the Custom Outline 2-Layer FR4 Rigid PCB with HASL Surface Finish, 1.6mm Thickness, White Solder Mask, Half-Ounce Copper Weight is a proven solution that balances cost, manufacturability, and design flexibility. Built on a standard FR4 substrate, this 2-layer rigid PCB offers stable electrical performance, dependable mechanical strength, and broad compatibility with mainstream assembly processes. The 1.6mm thickness (1.6+/-0.16mm) supports common enclosure and connector requirements, while the half-ounce copper weight (H/H OZ) provides reliable conductivity for standard signal and power applications. A HASL surface finish improves solderability and helps protect exposed copper from oxidation during storage and assembly. The white solder mask adds strong visual contrast for inspection, branding, and component placement accuracy. For projects that need a non-standard shape, this custom outline PCB is especially valuable because it supports unique mechanical constraints without sacrificing quality or repeatability. With price advantage and customization service, this board is well suited for prototypes, low-volume production, and commercial electronics targeting the US and European markets.
Why This 2-Layer FR4 PCB Remains a Popular Choice
Even as multilayer and HDI boards gain attention, the custom outline 2-layer FR4 rigid PCB continues to be widely used because it is simple, cost-effective, and easy to manufacture. For many products, a two-layer structure is enough to support the required circuitry while keeping fabrication and assembly efficient.
FR4 remains the industry standard for general-purpose rigid PCBs due to its dependable insulation properties, mechanical stability, and competitive cost. When paired with a clean custom outline, it becomes ideal for devices that need an irregular board shape, a tight enclosure fit, or a design that must avoid unnecessary material waste.
This makes the board suitable for:
Thickness-1.6+/-0.16mm for Mechanical Stability
One of the most important specifications in this board is Thickness-1.6+/-0.16mm. A 1.6mm board is considered the standard thickness for many rigid PCBs because it offers a strong balance between rigidity, assembly compatibility, and cost.
This thickness works well for:
For B2B procurement teams, using a standard thickness also makes sourcing easier because it aligns with common manufacturing workflows and widely available assembly fixtures.
Surface Finish-HASL for Reliable Solderability
The board uses Surface Finish-HASL, which remains one of the most practical and economical finish options for many PCB applications. HASL, or Hot Air Solder Leveling, provides a solderable surface and helps protect copper pads from oxidation.
Its advantages include:
Although finer-pitch designs may sometimes require alternative finishes, HASL remains highly suitable for many general electronic products where cost control and reliable assembly are priorities.
Copper-H/H OZ Supports Everyday Electrical Performance
With Copper-H/H OZ on both layers, this PCB provides enough copper for standard signal routing and moderate current-carrying needs. Half-ounce copper is often selected when the circuit does not require heavy current but still needs reliable conductivity and manufacturability.
This copper weight helps achieve:
For products that do not need thick copper, this is an efficient engineering choice that supports commercial viability without overengineering the board.
White Solder Mask Improves Visibility and Presentation
The Solder Mask Color-White is both functional and visual. From a technical standpoint, the solder mask protects traces and pads from oxidation, contamination, and accidental solder bridging. From a production standpoint, white solder mask provides strong contrast for inspection and component placement.
This is especially useful for:
White solder mask can also help the final product look cleaner and more premium, which is useful for customer-facing electronics.
Custom Outline Design Adds Real Project Value
A major advantage of this board is its custom outline capability. In many projects, the PCB cannot be a simple rectangle. It may need to fit a curved housing, avoid mechanical interference, or match an existing product architecture.
Custom outline fabrication allows engineers to:
For OEM and ODM projects, this flexibility often becomes a deciding factor when choosing a PCB supplier. It shows that the manufacturer can support not only the electrical design, but also the mechanical requirements of the final product.
Why This Board Fits B2B Procurement Needs
For procurement departments and engineering teams, the best PCB is not always the most advanced one. It is the one that meets the required specification consistently, at the right cost, with predictable lead time.
This Custom Outline 2-Layer FR4 Rigid PCB with HASL Surface Finish offers exactly that:
That combination makes it a smart option for prototype development, sample runs, and stable production.
FAQ
What is a custom outline PCB?
A custom outline PCB is a board manufactured in a non-standard shape to fit specific mechanical, housing, or product design requirements.
Why choose FR4 for a 2-layer rigid PCB?
FR4 is cost-effective, mechanically stable, and widely used in general electronics, making it a practical choice for many standard applications.
Is HASL a good surface finish?
Yes. HASL offers reliable solderability and strong process maturity, making it suitable for many general-purpose PCB designs.
What does 1.6+/-0.16mm thickness mean?
It means the PCB has a standard 1.6mm board thickness with an allowed tolerance of ±0.16mm.
Why use half-ounce copper?
Half-ounce copper is often sufficient for standard signal and moderate power applications while keeping manufacturing costs efficient.
