2 Layer Flexible PCB Assembly for LED

♦ What is Flexible PCB Assembly?

Flexible PCB Assembly (Flex PCBA) is the process of mounting and soldering electronic components onto a flexible printed circuit board (Flex PCB)—a bendable, lightweight alternative to traditional rigid PCBs. These assemblies are used in applications where flexibility, space savings, or dynamic movement is required.

✔ Bendable & Lightweight – Can be folded, twisted, or shaped to fit tight spaces.
✔ High-Density Interconnects – Supports complex circuitry in compact designs.
✔ Durability – Resists vibration, shock, and mechanical stress better than rigid PCBs.
✔ Thin & Light – Ideal for wearable tech, medical devices, and aerospace.

♦ Flexible PCB Assembly Process?

1. Flex PCB Fabrication

- - Made from polyimide (PI) or PET materials (instead of rigid FR4).
  - Layers include:
    - Conductive traces (copper)
    - Adhesive layers
    - Coverlay (protective film, like solder mask)

2. Solder Paste Application (SMT for Flex PCBs)

- - A laser-cut stencil applies solder paste to flexible PCB pads.
  - Challenges:
    - Flex PCBs are thin and may warp during soldering.
    - Requires precise temperature control.

3. Component Placement

- - Pick-and-place machines mount SMD components (resistors, ICs, etc.).
  - Critical:
    - Avoid placing large components near bend areas.
    - Use stiffeners (rigid supports) where needed.

4. Reflow Soldering

- - Lower peak temperatures (~230–250°C) than rigid PCBs to avoid damaging polyimide.
  - Controlled heating/cooling prevents warping.

5. Through-Hole Assembly (If Needed)

- - Flex-rigid PCBs may have plated through-holes (PTH).
  - Manual soldering is often required for THT parts.

6. Inspection & Testing

- - Automated Optical Inspection (AOI) – Checks for misalignment or solder defects.
  - X-ray Inspection (AXI) – Examines hidden joints (e.g., under BGAs).
  - Flex Testing – Verifies durability under bending/stretching.

♦ Types of Flexible PCB Assemblies?

Type	Description	Applications
Single-Sided Flex PCBA	Components on one side.	Simple wearables, sensors.
Double-Sided Flex PCBA	Components on both sides.	Cameras, medical devices.
Multilayer Flex PCBA	3+ conductive layers.	High-speed electronics (5G, aerospace).
Rigid-Flex PCBA	Combines rigid and flex sections.	Foldable phones, military systems.
