报价请写清楚两点:
1. 工厂合作方式(是否需要定制费用, MOQ, 单价)
预计采购数量:
5,000-10,000 PCB (150,000-300,000 传感器)in 2017. 每个pcb 上镶嵌30个接近霍尔传感器
2017 年以后的采购量50,000-100,000PCB system, ( 1500,000-3000,000 传感器)每年。
2. IP 外包方式 (提供可估量的样品, 图纸,工作原型, 物料清单, 可供生产的一切资料)
可以同时报两种合作方式
两种报价均提供, 时间, 付款方式, 项目经验
1. 分辨率: 1微米
2. 量程(测量范围):0-200微米
3. 传感器尺寸: 3-4 mm,
4. PCB尺寸: 总长 180mm, 宽10-15mm
5. 输出:串行输出(通过SPI接口传输数据)1 serial output. Every 250 microsecond we need to send a string:(Channel1[12 Bit], Channel2[12 Bit],…..., Channel30[12Bit])
6. 通道: 30个通道,
7. 抽样:30通道,总共250微秒 (Sampling -250 microsecond for all 30 channels together)
8. 成品:PCB(印刷电路板)。 一面是30个磁霍尔接近传感器, 另外一面是电子( From one side – Hall Sensors. From another side – the electronics. )
9, 工作环境: 室内, 无油无烟。
解释:
一面有30个磁霍尔传感器镶嵌在PCB上,另一面是electronics。 每个磁霍尔传感器装在一个金属球轴承旁,每个球轴承最多可以移动0.2mm(200微米), 总共有30个球轴承,每个磁霍尔磁性传感器可以感觉到球轴承的运动,用1微米的精度来测量运动。30个信号从30个磁霍尔传感器发送到电子板,这30个信号需序列化成一行。每行到达250 微秒, 可以通过SPI接口传输数据

5,000-10,000 PCB (150,000-300,000 sensors) in 2017,every PCB has 30 sensors mount on him, then up to 50,000-100,000 PCB per year.
Customization specification:
Multichannel magnetic Hall effect proximity sensor( have superior proximity stability )
Measurement range: 0-200 micrometers
Size for the sensor: 3-4 mm,
PCB Size: Totally size of the PCB is 180mm, width is 10-15mm
Output: Serial output ( SPI interface to transmit the data ) 1 serial output.
Every 250 microsecond we need to send a string:(Channel1[12 Bit], Channel2[12 Bit],…..., Channel30[12Bit])
channels: 30 channels
Sampling : 30 channel, totally 250 microsecond(Sampling -250 microsecond for all 30 channels together)
Completed product: PCB( printed circuit board) We need the PCB. From one side – Hall Sensors. From another side – the electronics. Probably, we will need a small additional PCB to be connected to OUR OWN electronic board: the RECEIVER.
Explanation:
(this PCB should contain 30 sensors from one side and the electronics from another side.The sensor should be mounted on PCB, each sensor is placed near a metal ball bearing,Each ball bearing can move a little, maximum 0.2mm, which is 200 micrometers.There are 30 ball bearings. Each magnetic sensor can feel the movement of the ball bearing.We need to measure this movement with the precision of 1 micrometer.It should be magnetic hall effect sensors. Then we need 30 signal ( from 30 sensors) to send to our electronic board. These 30 signals should be serialized into one line. Each line should come every 250 microsecond.The data can be transmitted through an SPI interface.)
