HKN Altium Workshop PCB Submit to Advanced Circuits Make Solder Mask Sides -> Both Sides Make Silkscreen Sides -> Both Sides Find Board Size -> Go Back to Project 9. Contact; Contact information; Thanks; King Sun PCB. This is done by going into Design -> Rules…. 对于 PCB 的设计, Altium Designer. Changes include: 1. Read about 'Can't change Paste and Solder Mask Expansion using Inspector' on element14. Non-Solder Mask Defined BGA Pads (NSMD) NSMD pads can be smaller than the diameter of the solder ball. I have created a solid region of the shape I desire. Click the Options button from the Edit Document window. Expansion value from rules - when this option is enabled, the paste mask expansion for this pad is defined by the applicable Paste Mask Expansion design rule. General primitives can generate solder and paste mask expansions. PcbDoc - 8051 LEDPrjPcb_ Licensed to PCB Paste Mask Expansion PasteMaskExpansion RoutingCorners 254mm 254mm FMKLCLINV 45 Degrees. Elements selected in canvas can be cancelled by 'Esc'. PCB Solder Mask Types All solder masks consist of a polymer layer that is applied over the metal traces on a Printed Circuit Board. Options are available to follow the expansion defined in the applicable design rule, or to override the rule and apply a specified expansion directly to the individual pad in question. Discover features you didn't know existed and get the most out of those you already know about. Size (px). В поле Paste Mask Expansion. PcbDoc - 8051 LEDPrjPcb_ Licensed to PCB Paste Mask Expansion PasteMaskExpansion RoutingCorners 254mm 254mm FMKLCLINV 45 Degrees. Via Connection at the Bottom of the Copper Plane SLOA122- July 2006 QFN Layout Guidelines 3 Submit Documentation Feedback. My idea was to somehow "tag" the footprints in my library that I feel need shrinking and then set up paste mask expansion rules to only affect the footprints with a matching tag, that would allow me to define different categories of. Then the board will immediately fail the end-of-line go-nogo test. paste mask 业内俗称“钢网”或“钢板”。. I want to gold plate these pads, as is normally done with these type of connectors. As a result of the very first BugCrunch report that was voted in, this latest update adds the ability to add solder and paste mask expansion rules to regions, fills, and tracks. Specify expansion value - Enable this option to override the rule and specify the paste mask. Set the paste mask expansion fixed to 0mm, and the soldermask expansion approximately equal to the pad radius, so it becomes twice the diameter. The default is for the pad to use the Expansion value from rules (the Paste Mask Expansion rule and the Solder Mask Expansion rule), this can be overridden and local values defined directly in the Pad. Do not use a thermal relief web or spoke connection which impedes the conduction path into the inner copper layer(s). For early Altium designer, go into your PCB design and create the gerbers. If I follow a 4 mil solder mask expansion guideline around pads I will have little less than 2 mil left between solder masks on neighboring pins. Top solder Top Paste solder mask paste mask Which one is the green mask usually used to protect tracks. Here are some differences between solder mask and paste mask: 1) The openings on solder mask layer have no solder mask ink, but the openings on paste mask layer have paste. Solder masks are critical for wave soldering, which is a mass production technique. 如图所示,在VD的下面出现了红色.
