What is Quick Turn Rigid Flex PCB?

The Quick Turn Rigid Flex PCB is a printed circuit board (PCB) type that combines a flex PCB’s flexibility with the rigidity of a rigid PCB. It provides the advantages of both rigid and flexible circuits in a single package, enabling greater design flexibility and reducing the cost and complexity of the overall system.

The Quick Turn Rigid-Flex PCB Manufacturing Process

Rigid Flexible PCB

The manufacture of a quick turn rigid flex PCB involves the following steps:

1. Preparing the Base Material

Preparing/cleaning the laminate is the first stage in the manufacture of the board. Before using further manufacturing methods, engineers need to carefully clean the laminate including a copper layer with an adhesive.

2. Circuit Pattern Generation

These days, circuit pattern generation is taking place in the following two methods:

  • Screen printing – This method is common since it can produce the necessary circuit patterns/deposits directly onto the laminate’s surface. Not more than 4 to 50 microns thick overall.
  • Photo Imaging – In this technique, the laminate is in close contact with a dry photoresist sheet that contains the necessary circuitry. Engineers then transfer the design from the photomask to the laminate by subjected the assembly to UV light. The laminate with the desired circuit layout then remains after the engineers have chemically removed the film.

3. Etch the Circuit Pattern

After the production of the circuit pattern, engineers then etch the copper laminate containing the circuit pattern. They either dip the laminate in an etch bath or spray it with an etching solution. To get the required results, they etch both sides of the lamination simultaneously.

4. Drilling Procedures

The manufacturers must now drill the necessary number of holes, pads, and vias. To drill precise holes, they employ high speed equipment. Also, they use laser drilling techniques to produce incredibly small holes.

5. Through-hole plating

Once they have bored the holes to the necessary specifications, they chemically coat them, then put copper in them. This creates electrical connectivity from layer to layer.

6. Apply Cover Lay or Cover coat

It’s important to apply Cover Lay or Cover coat to the top and bottom sides of the flex circuit to protect them. By doing this, you protect the circuit from damaging weather, strong chemicals, and solvents.

7. Cutting out the Flex

Next, the engineers proceed to blanking or cutting out each individual flex board from the production panel. Hydraulic punching typically helps manufacturers to produce rigid-flex PCBs in large quantities. Conversely, small production runs of prototype rigid-flex PCBs involves a specialized blanking knife.

8. Electrical testing and verification

The boards go through rigorous electrical testing for circuit performance, quality, and circuit performance in relation to the design criteria. A variety of testing techniques such as grid and flying probe tests exists.

Pros Of Quick Turn Rigid-Flex PCB

Quick-turn rigid-flex PCBs offer the following benefits to their users:

  1. Improved Reliability: Since this type of PCB incorporates rigid and flexible components, it can withstand higher levels of vibration and shock than traditional PCBs. This feature makes it ideal for use in applications where high levels of vibration and shock are a possibility.
  2. Cost Savings: Compared to traditional PCBs, these boards are less expensive to produce. This aspect is due to their simplified design and reduced number of layers. As a result, manufacturers can save money on material costs, labor costs, and development time.
  3. Faster Turnaround Time: Quick-turn rigid-flex PCBs offer shorter turnaround times than traditional PCBs. This feature is because they require fewer layers, which reduces the time needed to design and manufacture them. As a result, manufacturers can quickly bring their products to market and reduce their time.
  4. Design Flexibility: Quick-turn rigid-flex PCBs offer a high level of design flexibility. This aspect is because these boards can accommodate components of various sizes and shapes, allowing for more design options.

Cons Of Quick Turn Rigid-Flex PCB

Despite their numerous merits, quick-turn rigid-flex PCBs come with the following demerits:

  1. Cost: Quick-turn rigid-flex PCBs are more expensive than traditional rigid PCBs. They require more complex processes and materials to construct, so they can appear cost prohibitive. This fact is especially actual for small production runs.
  2. Space: Quick-turn rigid-flex PCBs require more space than traditional rigid PCBs. The flexible portion of the board needs more surface area to bend around and is usually thicker than rigid PCBs, which can take up more space when installed in an enclosure.
  3. Design Limitations: Quick-turn rigid-flex PCBs also have design limitations that can be difficult to work around. The flexible portion of the board typically requires more space than the rigid portion, so the placement of components can be low. In addition, the number of layers and the size of features is also low.
