What is the minimum solder mask sliver?
0.1 mm
Minimum “Solder Mask Sliver” means the pip of Soldermask between the pads. In our specifications we declared the thickness with a minimum of 0.1 mm. In example for PCB-POOL orders: The applied solder pad is increased 0.075 mm around the copperpad.
What is solder mask clearance?
Solder mask clearance is a tolerance to decide how close the solder mask can be to the PCB surface features. The purpose of this tolerance/clearance is to provide adequate spacing known as solder dams between surface features that receive solder. This prevents the formation of solder bridges.
What is net antenna in Altium?
This rule operates at a net level in the design to flag any open-ended track/arc primitive, or open-ended track/arc that is terminated with a via, and thus forms an antenna. All design rules are created and managed within the PCB Rules and Constraints Editor dialog.
What is solder mask defined pad?
Soldermask defined pad (SMD) is that the solder mask is coated on the some copper foil and the copper foil which is not masked forms the pad. The soldermask openings are smaller than copper pads. The solder mask covers the pcb area between adjacent pads and overlaps on top on pad edges.
What is net antenna?
The Volleyball Net Antenna gives volleyball players and referees a visual aid to judge whether or not a ball is in play or out of bounds as it travels over the net. The Volleyball Net Antenna are sold in pairs.
Is there a silk to solder mask clearance rule?
SILK TO SOLDER MASK CLEARANCE DESIGN RULE. This release sees the arrival of a new “Silk To Solder Mask Clearance” design rule, with new checking modes (to exposed copper, or to solder mask openings). Silkscreen Over Component Pads rules in existing designs are auto-converted with parameters set to match legacy behavior.
Can a PCB be converted to silk to solder mask?
When loading a PCB document from such an earlier release, any defined Silkscreen Over Component Pads rules will automatically be converted to Silk To Solder Mask Clearance rules, with their scopes and constraints set to match legacy behavior.
What’s the minimum clearance between silk and copper?
Silkscreen To Object Minimum Clearance – specifies the minimum permissable clearance between a silkscreen object and either exposed copper, or solder mask openings, depending on the clearance checking mode chosen.
How big does a solder mask expansion need to be?
Generally an expansion of 0.002 inches (0.051 millimeters) is sufficient, but if you have space you could increase that a bit. The required distance between soldermask openings will depend on your board supplier and their requirements.
