But like any technology, flexible PCB assembly brings both impressive advantages and unique challenges.

At BoardAssembly.com, we specialize in delivering high-quality flexible PCB solutions tailored to meet the exact specifications of our clients. Here’s what you need to know if you’re considering flexible PCB assembly for your next project.

Benefits of Flexible PCB Assembly

1. Design Versatility

Flexible PCBs can bend, twist, and fold, making them ideal for applications where space is limited or irregular. Their lightweight and thin profile enable designers to build products that are more compact, ergonomic, and durable.

2. Space and Weight Savings

Compared to traditional rigid boards, flexible circuits significantly reduce the overall weight and size of the electronic assembly. This is crucial in industries like aerospace, military, and medical technology, where every gram matters.

3. Improved Reliability

Because they eliminate the need for connectors and cables between separate rigid boards, flexible PCBs reduce connection points—one of the most common sources of failure. Fewer solder joints also mean fewer opportunities for mechanical failure.

4. Cost-Effective for Complex Assemblies

Although the upfront costs may be higher, flexible PCB assemblies can ultimately reduce the total cost of ownership by consolidating components and simplifying assembly processes, especially in high-density designs.

Challenges of Flexible PCB Assembly

1. Complex Manufacturing Process

The materials and manufacturing techniques required for flexible PCB assembly are more advanced than for traditional rigid boards. Precise handling, specialized equipment, and expert design are necessary to avoid defects.

2. Higher Initial Costs

Due to the specialized materials and processes, flexible PCBs generally cost more to prototype and manufacture than standard PCBs. However, these costs are often offset by savings in assembly and system integration over time.

3. Thermal and Mechanical Sensitivity

Flexible boards are more susceptible to damage from excessive heat or mechanical stress during the assembly process. Controlled environments and skilled technicians are crucial to maintaining the integrity of the board.

Is Through-Hole Assembly Still Important to Use?

 

Before the 1960s, the through-hole assembly process for mounting components onto printed circuit boards was the only game in town. It was labor-intensive and required a lot of space, but it was the only option. That all changed with the rise of surface mount technology (SMT), which allows for components to be mounted directly onto a printed circuit board’s surface. Since SMT doesn’t require drilling holes through a PCB, its components are much smaller and can be mounted on each side of the board. The result is a denser, smaller PCB that can perform much better than a PCB using through-hole technology.

When SMT came on the scene, many engineers believed it would harken the death of through-hole PCBs. However, while SMT does reign supreme, through-hole is still with us today. In very specific circumstances, through-hole PCBs are a better choice than their SMT counterparts.

A Few Important Uses for Through-Hole PCBs

Through-hole PCBs may be bigger and clunkier than SMT PCBs, but they do offer up one important advantage. Through-hole components are attached far more securely than SMT, which gives them a much stronger connection between layers. SMT connections are strong enough for the vast majority of products that people use in their day-to-day lives, but for machines that must operate in extreme environments, through-hole is the more reliable and stable option.

For example, through-hole PCBs can be commonly found in machines in the military and aerospace industries. Oftentimes, these machines must survive extreme temperatures, forceful collisions, and rapid accelerations. Through-hole is the ideal reliable and resilient mounting option for these types of products.

Prototypes

The other area where you are most likely to find through-hole mounting is in product prototypes. Through-hole is often preferred in prototyping, because it is much easier to adjust and replace components as the prototype undergoes testing and design alterations. If you are dreaming up an exciting new product, you’ll want to reach out to a printed circuit board vendor that is adept at through-hole mounting. This will give you more flexibility as you put the prototype through its paces.

Find Your SMT and Through-Hole Vendor

No matter what your industry or product line, it is smart to look for a printed circuit board manufacturer with both SMT and through-hole experience. This will allow you more choice and more control over your final product. At ACME PCB Assembly, we offer extensive experience in both SMT assembly and through-hole assembly.

ROHS-Compliant Assembly Services USA

How Being RoHS-Compliant PCB Assembly Services are Different from Assembly Services?

With everyone’s increasing concerns on the over usage of hazardous materials in the electronic and electrical products and their environmental impact, there have been several stricter regulations being imposed by the leading governmental organizations across the world. The RoHS compliance is one of those important regulations that is currently being imposed on the utilization of hazardous materials in the electronics and electrical products. Are you interested in knowing how this compliance works or what the benefits are?

Being Able to Understand the Materials that are Restricted Under RoHS Compliance

The RoHS compliance has restricted the use of six materials in the PCBs and electronic items. They include Mercury (Hg), Lead (Pb), Cadmium (Cd), Hexavalent Chromium (CrVI), polybrominated diphenyl ethers (PBDE), Polybrominated biphenyls (PBB), and phthalates such as BBP, DEHP, BBP, and DIBP.

The compliance also specifies the maximum levels of these restricted materials in the PCBs and other electronics items.

  1. Mercury (Hg): < 100 ppm
  2. Lead (Pb): < 1000 ppm
  3. Cadmium (Cd): < 100 ppm
  4. Polybrominated Biphenyls (PBB): < 1000 ppm
  5. Hexavalent Chromium: (Cr VI) < 1000 ppm
  6. Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
  7. Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
  8. Dibutyl phthalate (DBP): < 1000 ppm
  9. Diisobutyl phthalate (DIBP): < 1000 ppm
  10. Benzyl butyl phthalate (BBP): < 1000 ppm

The Many Features of RoHS-Compliant Assembly Services

Many PCB assembly services are utilizing processes and technologies that help them manufacture RoHS-compliant PCB assemblies. The following are a few features that help distinguish these services from others.

  • Lead-free Surface Finishes:Many manufacturers are nowadays using lead-free surface finishes such as lead-free HASL, ENIG, Electroplated Nickel and Soft (Bondable), Hard Gold Immersion Tin (White Tin), and Organic Solderability Preservatives (OSP).
