Background
Syrostan project aims to test the quality and find out potential problems of the sinara project hardwares manufactured by the factory. A lever is used to fix the cards and probe necessary test points through pogo pins. The document gives a guide on how to order these tailor-made levers for each card (taking DIO-SMA as an example) from Taobao.
Basic information
- Taobao shop: 深圳市精创新科技
- Item link: 测试架PCB测试架工装PCB测试治具定做夹具模块FPC测试架测试夹具
- Need ~1 week for manufacturing
- Price mainly based on numbers of test points (need to confirm with the manufacturer, for the DIO-SMA case, they charged 400RMB for 60 test points)
- Ask them to ship to HK directly using SF-express (weight ~5kg, shipping fee 70~120HKD)
Documents needed
-
Altium Designer PCB project file (available on https://github.com/sinara-hw)
-
Photos of the actual card with marks to specify where the test points are.
-
Specify the shapes of the test points if necessary (especially for special shapes), such as holes, pads, holes with solder, pins of components, etc.
-
Specify which holes can be used to support the board (for DIO case, 4 screw holes are used)
-
The 3D cad file and photo of the Syronstan PCB (to show them the positions of screw holes)
Cad file could be exported from https://git.m-labs.hk/sinara-hw/Syrostan-HW
Ordering steps
-
Contact their customer service directly, providing them with the following:
-
Pogo pins will occupy 15MM of inner space of the base box. A total height of 100MM should be enough to place the Syrostan board.
-
Can ask them to add necessary buttons on the panel, especially one for detecting the pressing.
-
Can ask for a dxf file of the holes on the acrylic they manufactured to import to KiCad for the extension PCB board.
-
Ask them to take a video preview before shipping to us.
-
Extension board can refer to this example for DIO-SMA. https://git.m-labs.hk/sinara-hw/Syrostan-Ext-DIO
-
The pogo pins are standard 2.54mm dupont pins. Connect the pogo pins and extension board with general female dupont connectors.
