One, line

1. minimum line width: 6mil (0.153mm). That is to say, if less than 6mil line width will not produce, (multilayer PCB inner line width line distance minimum is 8MIL) if the design conditions permit, the more the better the design, the larger the line width, the better the production, the higher the good, the general design is about 10mil, this point is very important, the design must consider.

2. minimum line distance: 6mil (0.153mm). The minimum line distance, line to line, line to weld plate distance is not less than 6mil from the production point of view, the greater the better, the general routine in the 10mil, of course, the design conditions, the greater the better this point is very important, the design must consider.

3. line to contour line spacing 0.508mm (20MIL)

Two, via hole (the commonly known conductive hole)

1. minimum aperture: 0.3mm (12mil)

2. minimum hole (VIA) aperture is not less than 0.3mm (12mil), and the single side of the weld plate can not be less than 6mil (0.153mm), preferably larger than 8mil (0.2mm). This point is very important, and the design must be considered.

3. through hole (VIA) hole to hole spacing (Kong Bian to Kong Bian) can not be less than 6mil, preferably greater than 8mil. This point is very important, and the design must be considered.

4. weld plate to contour line distance 0.508mm (20MIL)

Three, PAD pad (commonly known as plug-in hole (PTH))

1. the size of the plug-in hole depends on your component, but it must be larger than your component tube foot. It is suggested that the minimum 0.2mm is more than 0.6 of the component pipe, and you must design at least 0.8 to prevent the machining tolerance from inserting.

2. Plug-in hole (PTH) pad outer ring unilateral can not be less than 0.2 mm (8 mil) of course, the larger the better, this is very important, design must be considered.

3. Plug-in hole (PTH) hole to hole spacing (hole edge to hole edge) can not be less than: 0.3 mm of course, the larger the better, this is very important, design must be considered.

4. weld plate to contour line distance 0.508mm (20MIL)

Four. Anti welding

The opening of the plug-in window can not be less than 0.1mm (4mil) on the SMD window.

5. Characters (Character design, a direct impact on production, the character is clear or not in character design is very relevant)

Character character width can not be less than 0.153mm (6mil), the word height can not be less than 0.811mm (32mil), the width ratio of the best ratio of the best 5 is also said, the word width 0.2mm word is high 1mm, to push the class.

Six: the minimum spacing of non metal slot slot is not less than 1.6mm, otherwise it will greatly increase the difficulty of milling.

Seven: Jigsaw

1., there are no gap jigsaw and gap, and the gap of the gap is not less than 1.6 (plate thickness 1.6) mm. Otherwise, the size of the hard plate is not the same, the gap of the gap in the gap of 0.5mm is generally 5mm.

2. the size of the V-cut direction must be greater than 8cm, because the V cut less than 8cm will fall into the machine, the V-cut width must be less than 32cm, and the width will not go into the V-cut machine. This point is limited by the production process, not we can't do it.

3. V-cut can only walk straight line, because of the shape of the board, it can not walk straight line can be used as a stamp hole bridge connection with spacing, related matters needing attention.
