LSM9DS1的土地格局？

LGA引脚间距意味着引脚之间的开放空间。
关于过大的垫子并不是那么简单。
我想要获得最好的质量和可重复性，你必须与之讨论
PCB制造商和装配厂。如果您计划批量生产，则应进行测试批次以验证您的制造过程的设计和可靠性。
根据我的知识和经验，我只能给你我的建议。如果装配将由机器完成，不要过大的垫。如果你手工组装过大的长度
 垫片的厚度为0.1毫米
宽度仅0.05毫米。



以下为原文




LGA pin spacing means open space between pins.
Concerning the oversizing the land-pad is not that simple.
I you want to get the best possible quality and repeatability you have to discuss this with
PCB manufacturer and assembly plant. If you plan a mass production you should make a test batch to validate your desing and reliability of manaufacturing process.


I can give you only my recommendation based on my knowledge and experiences, If the assembly will be done by machine, do not oversize the pads. If you will do the assembly by hand oversize the length
of the land pads by 0.1 mm and the
width by only 0.05 mm.

谢谢！事实上，我意识到与工厂和装配的良好沟通对于大规模生产的成功至关重要。
对于这一系列的零件 - MEMS传感器 - ST Micro文档强调仔细的PCB和模板设计，以最大限度地减少测量误差和失真。这不是董事会或组装供应商有能力与之交谈的事情;他们只关心成功的装配，而不是一致的测量质量。
所以我非常感谢你的指导！再次感谢。

Thanks!  Indeed I'm aware of good communication with fab and assembly being critical to success of mass production.
For this family of parts -- MEMS sensors -- ST Micro documentation emphasizes careful PCB and stencil design to minimize measurement error and distortion.  This is not something the board or assembly vendors will have any ability to speak to; they are only concerned with successful assembly, not consistent measurement quality.
So I'm very grateful for your guidance!  Thanks again.
