First clarify what do you mean by "solder mask". The OBTACLE you draw or the PAINT on the board. It is a clasical use of word confusion. I am going to name SOLDER MASK the obtacle you draw in Orcad. Suppose you DO NOT want paint on the whole bottom layer (RF board a must), you want only finished metal exposed.

Sep 26, 2019 · SMBOC (solder mask over bare copper) as a process was developed to address the solder short problem. Here, solder or tin is stripped off the traces prior to the application of the solder mask. Since the solder mask adheres very well to bare copper it solves the solder short problem. In KiCad's Pcbnew, open the ZOPT220x Breakout and click on Dimensions -> Pads Mask Clearance. KiCad's solder mask clearance has a default of 0.2mm per side. We recommend you change this value to 0.1mm. Most fab houses will use 0.1mm as their default as well. You will then need to re-export your gerbers and load them back into GerbView. .

After setting a Solder Mask Expansion rule's scope as OnBottomSolderMask, Altium Designer could produce a fault followed by an abnormal termination. This issue has been corrected. Aug 25, 2015 · Problem is that solder mask is normally hard and take much time to scrap. You can’t put much force, so you have to scrape with nominal effort. To avoid any mishap, you can use pcb flux cleaner which is a chemical that can remove the solder mask from the upper surface of the circuit without harming it at all. You just need to know the quantity of chemical needed for removing the stain altogether. Eagle: Exposing copper / removing the Soldermask Does anyone know how you "expose" copper on the pcb in eagle? I have two polygons tied to signal lines that i want to turn into sort of buttons that you bridge with your fingers, but to do that i need the polygons "exposed", so the soldermask doesn't go over that area...

1299 Solder Mask expansion now updates correctly when updating a footprint from a PCB library. BugCrunch #3493. 1301 An access violation when Board Regions do not have a defined layer stack has been fixed through the investigation of a crash report. 1304 PCB Collaborate, Compare & Merge panel is now showing / matching layers correctly. This guide will explain how to take a Logo (or other simple image), that is in a digital format (BMP, JPG, PNG, etc), and turn it into a 2-tone Silk Screen Overlay in Altium Designer. The guide was created with AD10 but the process should be similar for other versions of Altium. File Requirements: In order to insure that you receive PCBs that meet your needs and expectations the following is a list of the files that we need to process your order efficiently and correctly. Please review your files in a Gerber viewer to insure that what you have submitted to be built is truly representative of your design files.

AVS 1.1 is now supported by Altium Designer 14.3. 3529: Component pads placed on a signal layer other than top or bottom could not be edited in certain layer-stack configurations, this no longer occurs. 3530: Top and Bottom Solder Mask layers are now included in the PCB Filter panel’s Layer list. 3546

You can set Solder Mask Expansion and Paste Mask Expansion as a negative value. No-official libs could also report errors. Elements selected in canvas can be cancelled by ‘Esc’. The position of the Footprints’ name of the PCB can be changed same as Prefix Position. Solder Bumps: Round solder balls bonded to the pads of components used in face-down bonding techniques. Solder Mask or Solder Resist: Coating to prevent solder being deposited on chosen areas of a board. Solder Wick: A band of wire removes molten solder away from a solder joint or a solder bridge or just for desoldering. I have included both top and bottom solder mask files. Solder mask swell is at least 0.008" larger than copper surfaces to keep mask off pads. Silkscreen: (if selected) I included a top silkscreen file and optional bottom silkscreen file (needed if added to order). Automated clipping performed on this service to remove silkscreen covering ...

In the via settings window you posted a screenshot of above, tick the checkbox "Force via tenting on top" (or bottom, depending on the side of the board your component is on). Altium will then remove the solder mask cutout from the top/bottom solder layer. Solder bridging checks the Top and Bottom layers against the Mask Top and Mask Bottom layers for the distance from the edge of the mask opening to any objects under the mask but on a different net from the pad exposed by the mask opening.

Aug 01, 2015 · Silkscreen to solder mask check. Altium designer 15, how to check silkcreen to pad in Altium Designer This video is my tip, I always use this tip for my projects.

If you want to create solder mask for the track, you can click the “Expose Copper” button at the right-hand property panel. The more information of routing, please refer at PCB: Route Tracks. Pad. You can add pads using the Pads button from the PCBLib Tools palette or using the P hotkey. For example, a 5mil Solder Mask Expansion applied to a 60mil diameter round pad will create a mask opening of 70mil (pad diameter + (2 x expansion)). If the reference is the hole edge, and the same pad had a hole diameter of 30mil, then the 70mil mask opening would be achieved by a 20mil expansion ( hole diameter + (2 x expansion) ).

Ultrafast PCB fabrication manufacturer in China, offering one-stop PCB prototype & production, PCB assembly, SMT stencil, components sourcing services online. §Solder Mask Application. Cleaning-The first step here is to clean the exposed copper surface pads, traces and through holes. Here, the surface is scrubbed using pumice. This helps to improve the adhesion of the mask and to remove surface contamination. Solder mask application-applying a photosensitive epoxy-based ink completely coats the panel.

I have to admit, I have never tried the new Orcad PCB Designer software (Added a note: I have used the previous combination: Orcad + Allegro L/XL for 5 years), but I spoke to a Cadence guy in February at Embedded world exhibition about it.

Solder mask color: Solder mask is available in different colors, but those colors can impact the manufacturability of the board. Green solder mask is the most widely used due in part to its superior properties, and it can reliably create the smallest solder dams over any other color. However, other colors may be preferred for specific purposes.

Jan 03, 2018 · As PCB assemblers, we’ve been asked the question,”Do I really need soldermask and silkscreen?” many times. And, we’ve been asked with good reasons. To us, soldermask protects exposed metal, reduce the chance of shorts and keeps solder where solder needs to be. Solder Paste Stencil Design Guidelines for Clean PCB Layouts Often, issues with your stencil will cause problems with the application of the solder paste.

Jul 22, 2019 · Solder mask has been used traditionally to prevent solder flowing away from AAD in a dog-bone footprint, possibly with through-hole vias. Instead, it is recommended to design with via-in-pad ... To add an intentional solder jumper, place the soldering iron's tip on the 3.3V side (left pad relative to the header pins facing down) and the center pad. If you decide to set the FTDI back to its default of 5V, simply heat the intentional solder jumper with a soldering iron and move the solder back to the right side.
