这一段时间论坛上印刷偏移问题较多,我把个人经历整理一下,上传让大家做一参考好的话大家多顶两下.

朋友只下载不顶一下,这样不好吧.好坏提个意见

此方法真的不错，兄弟应该是搞MPM的高手吧，可以留个联系方式有空聊聊啊！这么好的资料建义版主给点好评！

楼主你的东西我看过了,东西是不错不过我有几个问题要问下：虽然你这样做可以将Y方向的偏差调回来，但是你X方向的偏差怎么调？？？？因为调整X方向就必须要动到钢板，否则没法动。如果你动了钢板请问你的精准度又拿什么来衡量？？？另外你说：9，用JOG将Z轴降到VISION时的高度，这个高度是多少？？

很感谢你发贴！

首先谢谢这位老大提的意见.
1.MPM X Y 是都可以移动的无须动钢板.
2.<9，用JOG将Z轴降到VISION时的高度，这个高度是多少？？>此高度是在正常生产中Z轴上升后做VISION处理时的高度,具体是多少需要观察monitor中的显示了.这个高度有一点高或底不影响什么的.毕竟是在什么都没有的情况下进行的
3.注意第9,10项重复,下载后请删除多余项.这是我的失误

上棱镜到钢板的距离和下棱镜到PCB的距离为 0.16英寸

huyc-new	2005-12-26 14:36
我还没看,先给您顶一下,请大家珍惜别人的劳动成果,当然,有人不顶楼主也别减小您发贴的热忱.

下面是引用johnwang于2005-12-25 23:24发表的: 上棱镜到钢板的距离和下棱镜到PCB的距离为 0.16英寸那么我们在无治具的情况下该如何去确认这个距离呢？

johnwang	2005-12-26 20:41
拿一个 4MM的公制内六角 ,就可以了

johnwang	2005-12-26 20:43
6楼的兄弟??呵呵,讲话好象有点刻薄吗,难道指出缺点也是一种错误吗??

mslin	2005-12-26 23:58
楼上的想必有MPM的校正资料,何不拿出分享一下,MPM的电路故障我大都能够搞定,唯独调校欠缺,一无资料,二无治具. 我发现MPM的SERVICE ENG比较保守,不肯把资料拿出来共享,看看人家DEK,高级资料早就贡献出来了,并且买机器时VISION校正的STENCIL和PCB都有了.

johnwang	2005-12-27 20:33
呵呵,我最近在看DEK的技术手册感觉很不错,不过MPM嘛校正的资料确实比较保守几乎不会外泄的,抱歉我也帮不了你,原谅.

调校完后,需用PCB调校相机的焦距,一般供应商是用治具(大钢网和大PCB,上面有四个MARK点),如这位老兄所用之土方法,可以选一片较大的PCB及相对应的钢网,PCB上必须要有四个对称的MARK点,将此板做一个印刷程序,OFFSET为零,做好后,选择CAMERA CALIBRATION功能,按提示操作,即可校下相机的焦距.

When you want to run Vision calibrate ( C-tool , Vision calibration ) , you have to train by MPM calibration.You can get the whole calibration documents. If your company would like to pay money to calibrate your pick & place machines for a few days each one year ? Why you don't calibrate your printer ? By the way, if MPM provide you the whole calibration info without any tools , do you can run the calibration by yourself ?? Pleae think over!

lxx_smt	2006-01-13 22:03
我觉得楼主的方法是切实可行的，我们就是在没有治具的情况下做过，后来用治具校正检查ok的o

lxx_smt	2006-01-13 22:04
大家能够积极发挥积极主动性就是好样的！楼主好样的！继续努力啊！

manson.sun	2006-01-15 20:11
这种方法看起来在没有JIG的前提下还是切实可行的就是在调整VISION HEIGHT时还是不很清楚手动移动JOG的具体的程度下次尝试一下

ricky60	2006-01-17 06:18
总的来说挺不错的,这是一种挺好的思路

If you can provide whole calibation documents and toos, I am sure I can do any calibarion!
In fact most SMT engineer can read and understand those documents (calibration documents you mentioned, whatever Chinese or English version). If MPM can supply those relative calibration jigs to customer, I think it is very easy to take any calibration at customer site by their engineers or technicians.

elton	2006-01-18 03:36
Follow up the procedure of the whole calibration but you don't know which one do you have to do when the problem is happened. Do you know how many guys design the whole machine ? I am very sure you can follow up the procedure but you still not know the theory in detail.If you do unfinished ,it would be a big damage for your machine.

Sorry, i don't know there are any enigmatic theory in this area. :-)
In fact, i think a REAL MECHANICAL/ELECTRICAL ENGINEER should be good deel with any problem such as troubleshooting, maintenace, calibration and so on if enough information and tools be supplied.

Please kindly notes that all above letters are not aim at you or mpm or other mahines. I just find the ability of engineers is worse and worse in China area although the quantity of "engineers" is more and more. Do you think so?

way	2006-01-23 05:35
樓主的方法我還沒試過﹐不過感覺挺好的﹐有機會一定要試試。

不可预料的问题可能会发生！elton 说得有一定的道理，但理论和实践是相辅相成的！

yschee2008	2006-02-21 19:06
兄弟,此方法简单好用,不错的经验之谈,可我还没有真正了解MPM,所以还有待待于兄弟们的指点!

fox	2006-02-21 21:20
好资料能和大家分享，这是楼主靠经验总结出来的，值得我们这些刚入行的小弟学习啊！

jiangtao92	2006-03-17 15:19
谢谢,又多长几分见解.

lihaibo	2006-03-23 22:47
很高兴这位朋友能将自己的经验拿出来与大家一起分享.再次表示感谢!在这里还想请教你一个问题:我们公司用的MPM是UP2000,有几台这样的印刷机都会出现喷酒精不是很均匀(一头很湿,另一头却一点都没湿),检查酒精喷杆没有发现有塞孔的现象.还盼赐教!TKS!
