Oshpark PCBs for Optimal Solutions

The advancement of mobile electronic components has been nothing short of revolutionary. While the fabrication of miniature, smart electronic instruments can prove intricate, the utilization of versatile printed circuit boards has streamlined the production of complex electronic elements.

Flex PCB have proven to be particularly efficient in static and dynamic electronic devices, and as a result, many industries are incorporating them in the production of portable multi-functional devices. OSHPARK, a respected producer of flex PCBs, has solidified its standing for top-notch quality in the sector. In this piece, we’ll explore further into OSHPARK and their flex PCB.

What is OSHPARK?

OSHPARK is a well-regarded online platform providing fabrication and assembly services for printed circuit boards. It is a community-driven platform that enables hobbyists, makers, and engineers to design and order custom PCBs in small quantities at an affordable cost.  OSHPARK PCB, known for their distinctive purple-hued boards, have become a brand hallmark. The venture took off in 2011, and has since earned commendation for top-tier PCB provision with rapid delivery times. Broadly utilized within the electronics industry, OSHPARK PCB are first choice for prototype creation and limited-scale production of electronic apparatus.

History and Background of OSHPARK

OSHPARK was founded in 2011 by Drew Fustini, Laen O’Connor and Dave Young. The company was born out of frustration with the high costs and long lead times associated with low-volume PCB production.  the founders hope to devise a service enabling enthusiasts, inventors, and engineers to avail high-quality PCBs in smaller volumes at economical pricing.

The company’s name, “OSHPARK,” is a combination of “OSH” (short for “Open Source Hardware”) and “park” ( signify a community space). The founders of company believed that open-source hardware was a crucial part of the maker movement and wanted to create a platform that would support and encourage its development.

OSHPARK quickly garnered popularity within the creator community, recognized for their notable purple-hued circuit boards. The firm’s dedication to superior quality and exceptional customer service secured its differentiating space amidst widespread competition. Consequently, it has emerged as one of the most sought-after PCB fabrication services on the digital platform.

In 2018, OSHPARK was acquired by Advanced Circuits, a leading PCB manufacturer, but it continues to operate as an independent brand with its own unique identity and community.

OSHPARK PCB’s technologies and integration are designed to ensure that their PCB meet the highest industry standards. The company’s commitment to quality has earned it a reputation as a leading manufacturer of high-quality flex PCB.

Oshpark Flex PCB Types

Providing a comprehensive array of flex PCB types, OSHPARK caters to the extensive gamut of its client’s requirements. The offerings encompass the following types of flex PCB:

Single layer flex PCB: Incorporating a solitary conductive layer, these flexible PCB are distinguished by their simplicity. Their rudimentary design lends itself seamlessly to applications requiring a flexible and uncomplicated circuit layout.

Double sided flex PCB: Furnishing two conductive layers, these flex PCB offer enhanced design adaptability. Their dual-layer structure suits applications that demand a higher level of complexity.

In addition, the following are the minimum design rules for two-layer flex PCB:

● 6mil (0.1524mm): specified as the trace width.

● 5mil (0.127mm): denoted as the annular ring dimension.

● 6mil (0.1524mm): signified as the trace clearance.

● 10mil (0.254mm): characterized as the drill size.

Multi-layer flex PCB: These flexible PCB are characterized by three or more layers of conductive matter. The high-density circuit requisites of certain applications make multi-layer flex PCB an optimal choice.

Oshpark Rigid Flex PCB

the following are the minimum design rules for 4-layer flex PCB:

● 5mil (0.127mm): The prescribed measure for the trace width.

● 4mil (0.1016mm): The exact specification for the annular ring.

● 5mil (0.127mm): Designated value for the trace clearance.

● 10mil (0.254mm): Officially recognized standard for the drill size.

the following are the minimum design rules for 6 layer flex PCB:

● 5mil (0.127mm): Trace width is designated as such.

● 4mil (0.1016mm): This marks the annular ring‘s standard dimension.

● 8mil (0.2032mm): The drill size is defined by this measure.

● 5mil (0.127mm): This signifies the trace clearance for the design.

Rigid-flex PCB: These PCB exhibit a hybrid nature with sections both rigid and flexible. By amalgamating the advantages of both types of circuitry, rigid-flex PCB cater perfectly to applications that demand a synthesis of the two.

Sculptured flex PCB: These are flexible PCB with a unique three-dimensional shape. Sculptured flex PCB are ideal for applications that require a customized shape or fit.

OSHPARK’s range of flex PCB types allows clients to choose the type of PCB that best suits their specific application requirements.

Bend Radius of OSHPARK Flex PCB

Determination of the bend radius for a flex PCB, either in a static or dynamic state, is dependent on the thickness of all the layers present in the board that are affected by bending. This assessment is done by multiplying the board’s thickness by the bend ratio. A static bend is a process where the flex PCB is manipulated into a specific shape and subsequently installed while maintaining this curvature.

Contrastingly, a dynamic bend signifies the bending and straightening progression which a flex PCB experiences. Determining the bend radius for a dynamic bend may pose certain challenges, yet maintaining larger dynamic bends is essential to reduce wear during functionality. Conversely, brisk, dynamic bends could precipitate rapid PCB degradation.

Quality Assurance of OSHPARK

OSHPARK has a strong commitment to quality assurance and takes several steps to ensure that its PCB meet the required specifications and perform reliably.
