How to set DXP via cover oil 1. Double-click a via (via), 2. Left-click to select the via (via), then right-click Find Simillar Objects. (Note to check the red box option), then OK. 3. Check the red box option in the figure below, close the dialog box, and after exporting gerber again, there will be no vias (via cover oil) in the solder mask layer. Regarding the point of "via cover oil" and "via window", many customers often ask what this means when placing an order. The explanation for this issue is as follows: For some customers, the design is seriously non-standard, and they can't tell the difference between pad and via. Sometimes the conductive hole is processed with pad attributes, and sometimes the key hole is processed with via attributes. The design of VIA attributes and PAD attributes is confusing, resulting in incorrect processing. This is also one of the frequent complaints. For circuit board production factories, when processing CAM data, some film processing engineers, because of the non-standard design files of customers, will make the best of a bad situation and help customers modify the files, make the non-standard design correct, and process engineering data based on their own experience, which leads to and contributes to the non-standard design of customers. Conductive hole: via key hole: pad There are several problems that are particularly prone to occur: 1. Pads and vias are mixed up, leading to problems 1. When your file is pads or protel, send it to the factory and ask for via cover oil. Be careful. You should carefully check whether your plug-in hole (pad) also uses via. Otherwise, your plug-in hole will also be covered with green oil, which will cause it to be unable to weld. Point of dispute: The plug-in hole must be sprayed with tin. How do you cover it? How do I use it? When you say this, please check the file. Is it designed with pads or vias! 2. When your file is pads or protel, send the file to the factory and place an order for via cover oil. Many customers use pads (plug-in holes) to represent conductive holes, which leads to your conductive holes opening windows. Maybe you want via cover oil. At that time, the point of dispute may be, I want conductive hole cover oil, why do I open a window? Then please check your file design! Jia Li Chuang on this point: I have repeatedly emphasized that if you are via, treat it as via, and if it is pad, treat it as pad! Because no one will know that you have a conductive hole, that is a plug-in hole, and via and pad are the only identifiers. Please be clear! 2) During the conversion process of via, problems may occur due to non-standard design or unclear setting rules for gerber conversion. 3) When you send a gerber file, the factory cannot distinguish which are vias and which are keyholes. The only way to identify is to process according to the file. If there is a solder layer, there is a window! Point of dispute: I want vias with oil cover, and you have opened a window for me now. I may cause a short circuit. Please check your file. The gerber you send is a film file. The factory has no way to check whether yours is a conductive hole or a keyhole. Please check the gerber file to see if there is a solder layer. If there is, open a window. If not, cover with oil. 3: How to design via cover oil in protel or pads! ------This is the most standard practice. If the design is standard, there will be no mistakes! In protel, there is a tenting option in the via properties. If you check it, it must be covered with oil, so what you transfer out will be all covered with oil. In pads, the pads file needs to be covered with oil through the hole (via). The method is: when outputting the soldermask, that is, the solder mask layer, just check the solder mask top ---- the vias below, which means that all vias are opened. If it is not checked, the vias will be covered with oil. In summary: Pads are made according to pads, which are plug-in holes. You have two choices for vias. If you provide the original file, you will be asked to choose when placing an order. If you provide the gerber file, be sure to check whether the gerber file meets your requirements!
