【文章內(nèi)容簡(jiǎn)介】 close to the vcut that they will cause copper exposure. We suggest shaving the pads avoid to the copper exposure.，這種網(wǎng)格間距我們生產(chǎn)無(wú)法做到，.The copper grids on bottom side is only in some places,we can not do it per this gap,so we suggest decreasing the trace width to make copper grids to .6. 既然沒有功能上的影響，我們建議所有層附邊均加些銅皮以提高電鍍質(zhì)量。We suggest putting some extra copper on the waste tab in all layers to improve plating quality since this is no function effect.。We suggest putting some copper in blank area on top side to improve plated quality.，建議把它們連接起來。We have found that the gap between two block copper is only on bottom side,we suggest they are connected.9. 兩個(gè)光標(biāo)點(diǎn)處在vcut線上，它們將被削到。The two fiducial marks are over vgroove line . They will be cut . We suggest moving them toward the left . 四、孔層1. ，，但它們被定義成PTH孔，我們建議做NPTH孔The 2 holes with , 4 holes with and 4 holes with have no pads on top and bottom copper layer .But they are specified PTH in drill chart. We suggest build them as NPTH.2．這些孔（，,）被定義成PTH孔，但它們的焊盤與孔徑等大，我們建議做NPTH孔。These holes ( ,)are specified PTH .But they have pads which are the same as the holes in copper layer .We suggest them NPTH.，但它們的線路焊盤比孔大，我們建議做PTH孔。The 6 holes with are specified NPTH in drill chart .But they have pads which are larger than the holes in copper layers .We sugget them PTH .4. “的孔對(duì)應(yīng)的焊盤比孔大，但它們被定義成NPTH孔， ，請(qǐng)確認(rèn)The hole with have pad which is larger than the hole in top and bottom copper layer .But it39。s specified suggest shaving the pads around the confirm.，“的孔雙面沒有焊盤，”的孔為NPTH孔。The hole type(PTH or NPTH) did not be define in the Gerber, the two holes of diameter inch have not copper pads on both sides, we would like to confirm the two holes of diameter inch are nonplating holes, please confirm .，建議把他們制成槽孔。Some holes with are very close each other, we suggest doing them oval hole.、。There are two holes with mm and mm overlap each other in one place,we suggest only remain there.，而在鉆孔文件中孔數(shù)是290，請(qǐng)確認(rèn)孔數(shù)是290而不是291。The quantity of diameter inch in the hole chart of file DRD is 291, but(thruhole,tap) it is only 290. please confirm the quantity of diameter inch holes in the drill flie should be 290 not 291.*，但gerber中僅有兩個(gè)，建議按gerber制作。In the drilldraw file,it stated that the quantity of slots * is 4 ,but we have found two slots in the gerber file ,we suggest as per gerber file.。As no located holes for our routing,we suggest four additional holes with in waste tab.五、阻焊層1．在字符J3處， inch amp。 inch的孔兩面沒有開窗，未避免阻焊污染焊盤，在對(duì)孔雙面加開窗。On the location of J3,some holes of diameter inch amp。 inch have not mask opening on both sides, we would like to add mask opening for these holes to avoid solder resist encroach the solder pad on both sides.，為了避免油墨滲上焊盤，我們建議在BOTTOM面也加上與TOP面等大的阻焊開窗These pads have single side mask opening on the top side , we suggest extra mask opening on the bottom side with same size as pads to avoid mask onto pad.，我們認(rèn)為它們應(yīng)為元件孔。We found the 6 holes with have not soldermask opening on both sides. We think they should be ponent holes. We suggest putting solder mask opening on their pads on both sides.，這點(diǎn)我們應(yīng)該按原設(shè)計(jì)嗎？We found some fiducials without mask opening in
