Hi guys, I'm making pcb design with DR-QFN package and plan to make order for JLCPCB. Checked capabilities [here](https://jlcpcb.com/capabilities/Capabilities) and one think not clear for me. Please clarify if you known and can help. DR-QFN have two lines of pads: outer and inner.Clearance between outer pads = 8 mil or 0,20 mm. From requirements it's ok: ![img0.jpg](//image.easyeda.com/pullimage/TXMUjRd1xdQyAYJ9jcntEwFFTBc56mqWEbGySAow.jpeg) But for inner pads I must to create track only between two outer pads. Like in the picture: ![img1.jpg](//image.easyeda.com/pullimage/B4immriSloK54cgK7IKJJNLLgkJ8m3mWDkTvjlyA.jpeg) According JLCPCB Capabilities I see what Minimum allowed trace width and spacing will be 5mil (0.127mm) for 2 layers or 3.5 mil for 4+ layers in 1oz pcb. In my case it's requre 5 (spacing)+5(track)+5(spacing) = 15 mil or 0,38 mm between pins 48 and 50 what twise greater what I have for fabrication. Reference: ![img2.jpg](//image.easyeda.com/pullimage/Ul409UtcykQ5IAZWZYaWFWXzEiNMDkn0IArmBD5Q.jpeg) In this case looks like this chip and my requirements out of capabilities of JLCPCB. BUT(!): If I scroll down to BGA requirements I see min distance between balls = 5 mil or 0.127mm but what equals to minimal trace requirement abowe for 1-2 layers on only to 1,5 mil less what allowed to 4+ layers boards as I understood JLCPCB not expect what all balls will be floating without traces to some other pads because they not allowed by requirements. ![img3.jpg](//image.easyeda.com/pullimage/SMCkavAhnkmet2CQyDGmMjZpmcqEwqchewe9oSiJ.jpeg) How to understand this? Is requirement for spacing works only for traces but not working between trace and pad or ball? What is minimal spacing between pad and trace will be in this case? In my case I can forgot about spacing bettwen trace and pins or can forgot about order from JLCPCB?
