\"with<\/a><\/p>\n

We are really excited\u00a0to launch a new tool Online-DFM<\/a> today! \u00a0This tool can help to review your gerber and generate the DFM results in seconds. \u00a0 Let’s dig a bit deeper about this tool! \ud83d\ude42<\/p>\n

What is Online DFM?<\/span><\/strong><\/h3>\n

Online DFM is an online tool embedded with Seeed DFM list<\/strong> which will be able to help you identify the potential issues before you place the Fusion PCB\/PCBA order<\/a>. \u00a0Besides that, it also allows you to view the Gerber preciously and vividly. \u00a0What you see in the gerber viewer will be what you will get in your hand. \u00a0All you need to do is upload your Gerber and you will get an instant report.<\/strong><\/p>\n

With a good DFM guideline, you will be able to find the best spot in the manufacturing triangle<\/a> (Cost, Lead-time, Quality). \u00a0The ideal DFM tool can help\u00a0you identify the items below.\u00a0This list will be expand as we have more experience and feedback from clients.
\n1. Rounting<\/strong>
\neg. the minimum width of the traces connected to IC power are >6mil
\n2. Silkscreen<\/strong>
\neg. no silkscreen text on the solder pad
\n3. Footprint<\/strong>
\neg.component spacing restriction >7 mil
\n4. Via holes<\/strong>
\neg. all via under BGA should be filled by solder mask
\n5. Design for Manufacture<\/strong>
\neg. use DRC check before finishing the design
\n6. Design for test<\/strong>
\neg. Test vias are exposed<\/p>\n

WHY doing this?<\/span><\/strong><\/h3>\n

You may wonder why we choose to put such effort to do so, here are the reasons.<\/p>\n

1.<\/strong>\u00a0Online DFM is a TIME SAVER!<\/strong><\/p>\n

Fusion PCB and Fusion PCBA have more than 3000<\/strong> orders each month. \u00a0After we go through them one by one, normally 40% of them will be defective. \u00a0Some are lacking layers, some are short circuit, some are out of the manufacturing capability, etc. \u00a0This 40% order spend extra 1-2 days<\/strong> to modify it.<\/p>\n

What if we can help designer to identify major defects of these 40% before generating real order? According to our data analysis, lacking drilling layers causes 31% of the delay. So it is a mutual benefit for both of us to get it delivered on time.<\/p>\n

2. Quality assurance<\/strong><\/p>\n

The chart below shows you the analysis of the scattered defects.
\n\"defects\"<\/a><\/p>\n

Short circuit and Spacing problem rank 2nd and 3rd. \u00a0 They affect PCB quality. \u00a0We hope that the online-DFM will be able to identify most defects, shorten lead-time and enhance board quality.<\/p>\n

How to use it?<\/strong><\/span><\/h3>\n

Step 1. Go to\u00a0Online-DFM<\/a>, upload the gerber
\nStep 2. click Gerber Viewer<\/strong><\/h4>\n

\"2step\"<\/a><\/p>\n

 <\/p>\n

Then you are free to check each layer<\/p>\n

\"details\"<\/a>Also please pay attention to the top, it will give you the warning of your design, such as lacking drilling file.<\/p>\n
