10.1 Manufactured PCB Dimensions
[90] The range of dimensions allowed for each type of PCB construction is shown in table 11.

PCB dimensions and weight requirements

[91] Required PCB width-to-thickness ratio = Y / Z 150.
[92] Required PCB length-to-width ratio = X / Y 2.
[93] For board thicknesses of less than 0.8mm, the copper foil of should be evenly distributed to prevent board bending. If there are many small boards, use of a fixture is recommended.
[94] If the primary side does not meet the clearance area requirements, then the addition of a margin of a width
greater than 5mm, along the direction of travel is recommended.

PCB Dimensions Specification

Figure 56: PCB minimum margin dimensions.
[95] The body of components must not exceed past the edge of the PCB, and must satisfy the following:
The minimum distance from the edge of the solder pad (or component body) to the primary side
must be less than 5mm.
For non-reflow soldering, when a component protrudes out from the PCB, the width of the margin
is as follows:

For non-reflow soldering, when a component protrudes out from the PCB, the component must fit
into the margin with 0.5mm clearance as shown in Figure 58.
