PCB Assembly Services
From Prototype to Production – Precision Guaranteed
What is PCB Assembly?
PCB assembly is the process of populating a Printed Circuit Board (PCB) with all the required components. It includes:
-
DFA (Design for Assembly) analysis
-
Placement of surface-mount and through-hole components
-
Testing and final inspection
Attaching components to the PCB is the final step before using the fully operational electronic device.
What’s Needed for Efficient PCB Assembly?
To streamline your PCB assembly process, customers should provide:
-
A detailed Bill of Materials (BOM)
-
Assembly notes with:
-
Reference designators
-
Component orientation
-
Instructions for washable & non-washable parts
-
Methods of PCB Assembly
There are three main techniques used to create PCB assemblies. Each has its strengths based on the type of project.
1️⃣ Surface Mount Technology (SMT)
🔹 Components have conductive tabs that are soldered directly onto the PCB
🔹 Enables higher circuit density by placing components on both sides
🔹 Typically uses pick-and-place machines and reflow ovens
2️⃣ Through-Hole Technology (THT)
🔹 Components have leads inserted into pre-drilled holes
🔹 Assembled via wave soldering or manual soldering
🔹 Offers strong mechanical bonds, but higher cost and manual labor involved
3️⃣ Electro-Mechanical Assembly (Box Build)
Also known as box-build, this includes:
-
Wire harnesses & cable assemblies
-
Molded plastics
-
Metal enclosures
Used to combine the PCB with peripheral electronic hardware.
The Importance of Precision
Today’s electronics are rapidly evolving. With microelectronics gaining ground, precision in assembly determines the performance, durability, and efficiency of final products.
