DAOKAI WE-DA-065 PCB Ruler Set, 15/20/25 cm with Component References

When laying out a circuit board or checking the size of a component, the DAOKAI WE-DA-065 set puts measuring and common PCB design references within reach. It includes three rulers in 15 cm, 20 cm and 25 cm lengths, with millimetre and inch measurement plus reference details for component packages and IC pin spacing.

Use a standard ruler for straightforward length checks, or reach for this set when you also want quick PCB-related reference information alongside the measurement. The different lengths suit varied bench tasks, from checking smaller parts to measuring across a larger board.

Tech summary

• Set: One 15 cm, one 20 cm and one 25 cm PCB ruler
• Measurements: Millimetre and inch dimensions
• Angle measurement: 180 degrees
• IC pin spacing references: 0.5 mm, 0.65 mm, 0.8 mm, 1.0 mm, 1.25 mm and 2.54 mm
• Other references: Common bore diameters and SMD component package formats

The rulers combine everyday measuring with printed information for electronics work. Package references cover examples such as resistors, capacitors, diodes, inductors, crystals, LEDs and ICs, including formats such as 0603, 0805, SOP and LQFP. This makes the set useful for a quick visual reference while identifying or comparing common component package sizes, it complements measurement rather than replacing careful component identification.

Everyday compatibility

These rulers are designed around printed circuit board tasks, including measuring objects and looking up common component packages. For example, while planning a board layout, use a ruler to check a component’s dimensions, then refer to the printed IC pin spacing or package information as part of the same workflow. The integrated references can also help when sorting parts or comparing a component with a familiar package format.

The three lengths give you a choice of measuring surface for different jobs: the 15 cm ruler for compact checks, the 20 cm ruler for general bench use and the 25 cm ruler for longer measurements. Each remains part of one coordinated set, so you can choose the length that fits the area you are working on.

Getting the most from it

Keep the rulers close to your electronics workspace for measuring board layouts, checking component dimensions and consulting the printed reference details as you work. The 180-degree angle measurement adds another handy reference for PCB-related tasks, while the listed pin spacings help when comparing common IC layouts. Use the printed package information as a guide to familiar formats, alongside the actual measurements needed for your project.

When it makes sense

This set is a practical fit for electronics enthusiasts, engineers and manufacturers who want measuring tools with PCB-specific references in one package. It serves routine bench work where a plain ruler handles length but component formats, pin spacing or angle information are also useful. Choose the DAOKAI WE-DA-065 when a range of ruler lengths and quick access to common board and component references will support your measuring and planning tasks.
