Materials We Use for One Stop PCB Assembly Manufacturing
We use eight main PCB materials including FR4, Rogers, aluminum, copper core, ceramic, flex PCB and rigid-flex substrates for one stop PCB assembly projects.
Each material type handles different application needs from standard consumer electronics through high frequency RF designs and extreme temperature environments.
| Material Type | Description & Applications | Specifications |
|---|---|---|
| FR4 Standard | The most commonly used material for PCB fabrication. FR4 provides reliable performance for general purpose electronic products and offers excellent cost effectiveness for standard applications. | Glass transition temperature: 266°F to 356°F (130 to 180°C). Operating range: negative 40°F to positive 266°F (-40°C to +130°C). Dielectric constant: 4.2 to 4.6 @ 1MHz. |
| High-Tg FR4 | High temperature FR4 variant designed for lead free assembly processes requiring higher thermal stability. High Tg materials prevent delamination during reflow processing and extend operating temperature ranges. | Glass transition temperature: 338°F to 356°F (170-180°C). Operating range: negative 67°F to positive 302°F (-55°C to +150°C). Decomposition temp: greater than 572°F (300°C). |
| Flex PCB (FPC) | Flexible printed circuit board materials enable bending and folding within compact spaces. Flex PCB substrates connect moving parts while maintaining electrical performance through repeated flex cycles. | Polyimide base: 0.5 to 4 mil thickness. Flex life: greater than 100,000 cycles. Operating range: negative 328°F to positive 500°F (-200°C to +260°C). |
| Aluminum PCB | Aluminum substrates provide superior heat dissipation compared to FR4 materials. Aluminum PCBs suit high power applications requiring rapid thermal management, particularly LED lighting and power electronics. | Thermal conductivity: 1.0 to 2.0 W/m·K. Operating range: negative 40°F to positive 302°F (-40°C to +150°C). Dielectric strength: greater than 3000V/mil |
| Rogers Materials | Rogers substrates deliver advanced electrical properties for high frequency applications. When precise dielectric constants and low loss characteristics are needed, Rogers materials provide the solution for professional RF engineering. | Dielectric constant: 2.2 to 10.2 ± 0.02. Frequency range: DC to 77 GHz. Loss tangent: 0.0009 to 0.0035. |
| Ceramic PCB | Ceramic substrates handle extreme temperature applications beyond organic material limits. Alumina and aluminum nitride ceramics provide exceptional thermal conductivity and dimensional stability for demanding environments. | Thermal conductivity: 24 to 30 W/m·K. Operating range: negative 452°F to positive 3092°F (-269°C to +1700°C). Dielectric constant: 9.8 @ 1MHz. |
| Rigid Flex PCB | Rigid flex combinations integrate FR4 rigid sections with polyimide flex areas in single PCB designs. These materials eliminate connectors while enabling three dimensional PCB configurations for compact electronic products. | Impedance tolerance: ±5 to 10%. Twist & warp: less than 0.75%. Temperature cycling: negative 67°F to positive 257°F (-55°C to +125°C). |
What Is One-Stop PCB Assembly?
One-stop PCB assembly is a manufacturing service where one vendor handles PCB fabrication, component sourcing, and assembly operations for complete electronic assemblies. Customers work with one service provider instead of coordinating between a separate PCB manufacturer, component distributor, and assembly factory suppliers.
This approach delivers cost savings through bulk purchasing, faster assembly production, and consistent quality control across all manufacturing stages. Electronic products requiring PCB assemblies achieve faster time-to-market through one stop PCB assembly workflows.
What to Consider for Your One Stop PCB Assembly Design
Component Placement
Group similar component types together to reduce machine setup time while placing tall components away from smaller parts to prevent shadows during reflow processing.
Provide adequate space around BGA components for X-ray inspection access and keep components away from PCB edges to prevent damage during handling.
Solder Pad Design and Stencil Considerations
Avoid oversized pads that can cause solder bridging during reflow while making pads large enough to support reliable solder joints.
Consider stencil aperture requirements when designing pad layouts and maintain consistent pad sizes across similar components for uniform solder paste volume.
Thermal Management and PCB Materials
Choose High Tg FR4 for lead free assembly processes, flex PCB materials for bending applications, or copper core substrates for high power requirements.
Test Point Access and Assembly Testing
Design optical inspection targets for automated AOI systems and plan component placement for X-ray inspection access on BGA components.
Via Placement and Signal Integrity
Use via-in-pad designs only when necessary due to additional fabrication costs while positioning vias to support thermal management without interfering with assembly.
Route high-speed signals away from noisy components and use proper impedance control for important signal paths.
BOM Management and Component Selection
Choose components during the design phase to prevent conflicts and maintain up-to-date BOM information for accurate component procurement throughout one stop PCB assembly projects.

One Stop PCB Assembly Case Studies
PCB Assembly
A worker is concentrating on operating professional testing equipment to program and test the circuit board.
Programming is to load software code into the microcontroller or programmable device on the PCB, so that it can control various components on the circuit board and achieve specific functions.
Testing is to check whether there are defects in the manufacturing process of the PCB board and ensure that its functions and performance meet the design requirements.
PCB Assembly
We can also do the Case printing and production, also an important part in One Stop PCB Assembly.
You can provide us with 3D files, and we will produce prototypes and batches according to the files.
Before developing the mold, the first prototype will be made to check the appearance and function.

Hamid Reza Moshayedi
R&D Manager
Their work is very impressively perfect. Today, when they check our company PCB board after assemble. They found a fake short point which many engineers has never found in the past years. But that is just designed so. The PCB board quality is excellent. Their service is also excellent.
MikeZ
My friend introduced WellPCB to me, the first try, a little look forward to. I ordered a 47*72 10ps PCB, and I can’t wait to receive my PCB. So I used expedited service and received my PCB in three days. I tested and soldered the PCB, Quality is really good, silkscreen, plating also great.
