Custom PCB Design And Assembly SMT / Through Hole PCB Board Design

Overview

Modern PCBs increasingly combine SMT components for high-density circuits and through-hole components for mechanical strength and connectors. This mixed-technology assembly presents unique design challenges—placement order, soldering compatibility, and thermal management. Studio Electronics offers PCB Design for Assembly covering both SMT and through-hole technologies. As a premier provider of PCB assembly in China, our professional PCB layout engineers design layouts that accommodate both SMT and through-hole components efficiently, ensuring reliable soldering and high-yield assembly. Our 12 automated SMT lines and automatic wave soldering capability support mixed-technology boards from prototype to production.

Mixed-Technology Design – SMT & Through-Hole

Our Design-for-Assembly Process

Stage 1: Technology Assessment

We review your design requirements and determine the optimal mix of SMT and through-hole technologies. Component selection considers both electrical performance and assembly compatibility.

Stage 2: Layout with Assembly in Mind

Our PCB layout engineers position components to optimize assembly:

• SMT components on primary side where possible

• Through-hole components placed for wave soldering compatibility

• Adequate spacing for soldering and inspection

• Thermal copper balancing for even reflow

Stage 3: Design Review

A systematic assembly review verifies:

• Component clearance for placement tools

• Solder pad design for both reflow and wave soldering

• Thermal management for mixed technology

• Test point accessibility

Stage 4: Prototype Build & Validation

We fabricate 5-10 samples and assemble them on our 12 automated SMT lines. Through-hole components are processed through automatic wave soldering. Prototypes undergo AOI, X-Ray, and functional testing. Samples are shipped to you for confirmation.

Stage 5: Production

After approval, we scale to production—handling low volume PCB assembly or high-volume orders with the same mixed-technology expertise.

Why Design for Assembly Matters

• Higher Yield – Designs that match assembly processes

• Lower Cost – Efficient assembly reduces cost

• Reliable Soldering – Optimized for both SMT and through-hole

• Faster Production – Smooth assembly flow

• Mixed-Technology Support – Comprehensive capability for any board type

Studio delivers PCB Design for Assembly—SMT and through-hole optimized for reliable, high-yield production.
