What Is Mixed Technology PCBA Manufacturing?
Definition and Overview
Mixed technology PCBA manufacturing uses SMT and THT together. SMT places parts on the PCB’s surface. THT puts parts through holes and solders them. This mix lets you use parts of different sizes and shapes in one PCB.
PCB assembly has changed a lot over time. For example:
In the 1960s, integrated circuits (ICs) allowed multi-layer boards.
In the 1980s, SMT made assembly faster and better.
Today, rigid-flex PCBs and dense circuits are used in gadgets and electric cars.
Mixed technology PCBA builds on these changes, making it great for modern electronics.
Key Features of Mixed Technology Assembly
Mixed technology assembly has special features that improve PCB making:

How Does Mixed Technology PCBA Manufacturing Work?
Step-by-Step Process
The mixed technology PCBA process has many steps for quality results. Each step is important to make a strong and efficient PCB. Here’s how it works:
Design and Component Selection: First, design the PCB layout and pick parts. This step ensures the design fits the product’s needs.
PCB Fabrication: The PCB is made based on the design. This includes adding layers, traces, and holes.
SMT Assembly: Machines place small SMT parts on the PCB surface. These machines ensure parts are placed and soldered correctly.
THT Assembly: Larger THT parts go into drilled holes on the PCB. These parts are soldered by hand or with wave soldering.
Inspection and Testing: After assembly, the PCB is checked and tested. Tests make sure it works well in different conditions.
Metric | Description |
|---|---|
Counts defects per million chances, showing quality levels. | |
First Pass Yield (FPY) | Percent of PCBs passing all tests the first time. |
Rework Rate | Percent of PCBs needing fixes after assembly. Lower rates mean better quality. |
Scrap Rate | Percent of unusable PCBs due to defects. Lower rates mean higher productivity. |
Testing checks power, inputs/outputs, communication, and stress handling. These steps ensure the PCB is reliable and high-quality.
Integration of SMT and THT Components
Using both SMT and THT parts in one PCB needs careful planning. SMT parts are great for small designs, while THT parts are strong and durable. Follow these steps to combine them:
Component Selection and Inspection: Pick good parts to avoid problems during assembly.
PCB Preparation: Check the PCB for flaws before starting assembly.
Process Control: Keep the assembly process steady for consistent quality.
