Features

Blank Printed Circuit Boards (PCB) for Building Custom Electrical Circuits
Designed to Fit Inside Thorlabs' Compact Electronics Housings
PCBs Available in Tripad Layout or with Component Groups in Series
PCBs with Component Groups have Five Footprint Sizes in Parallel
- Wirewound
- 5 mm × 5 mm
- SMT1210
- SMT1206
- SMT0805
PCBs with Six Component Groups Also Offer Floating Positions for Larger Inductors

Thorlabs' Customizable Printed Circuit Boards (PCB) allow users to create their own passive electrical systems on boards designed to conveniently fit into our Extruded Aluminum Enclosures (see image above). The large grounding bars at the top and bottom of the board ensure a proper electrical connection with the enclosure and help to shield the circuit from external noise.

The EEAPB1 is a perforated circuit board for a custom electrical circuit of the user's own design. The blank circuit board has an array of Ø1 mm through holes with 0.1" spacing in a tripad layout, as shown in the image to the right; this standard grid spacing is ideal for common through-hole electronic components and is compatible with common IC packages. The other PCBs below contain multiple component groups in series with each other, with each component group consisting of 5 elements in parallel. For detailed electrical diagrams, please refer to the PCB Layouts tab. The footprints are designed to accept resistors (R), capacitors (C), or inductors (L). A variety of footprint sizes are made available in each group to accommodate several different types and sizes of electrical elements, including: wirewound, 5 mm × 5 mm, SMT1210, SMT1206, and SMT0805. Additionally, the board is compatible with edge mount BNC and SMA connectors. Please refer to the compatibility table above for more details. These PCBs are constructed from FR4 130tg and feature gold-immersed electrodes.

These printed circuit boards are ideal for creating simple, passive electrical circuits such as RC or LC filters. By incorporating multiple component groups, these PCBs are capable of supporting both 1^st and 2^nd order low-, high-, and bandpass filters, such as those demonstrated below. The PCBs with six component groups can also support 3^rd order designs. The examples below are not an exhaustive list of compatible circuits that one could build with this board. The exact design and elements are application dependent.

For applications that require very steep attenuation of stopband frequencies, Thorlabs also offers 5^th order elliptical low-pass and 5^th or 6^th order elliptical high-pass filters.

Perforated Printed Circuit Board

Zoom

This printed circuit board uses a tripad design with sets of three Ø1 mm through holes spaced 0.1" apart. The circuit board has no component group labels, allowing complete customization of the electrical circuit. It is compatible with a variety of SMD adapters, as well as edge-mount BNC and SMA connectors.

This PCB is 2.30" x 0.99" and is compatible with our EEA Series extruded aluminum housings.

Unpopulated Printed Circuit Boards with Component Groups

These blank printed circuit boards accept surface-mount components for a custom passive electrical circuit. The PCBs have either four (EEAPCB1) or six (EEB33PCB1 and EEB40PCB1) component groups with labels to assist in assembling the circuit. For details, see the PCB Layouts tab above. For compatibility with our extruded aluminum housings, see the table in the Overview tab above. The circuit boards are compatible with edge-mount BNC and SMA connectors.
