FAQ


What are the available holes sizes?


14 mils to 150 mils - 1 mil increments
150 mils to 200 mils - 5 mil increments
above 200 mils - holes would be routed out
We only use drills in imperial units. Files submitted in metric units (mm)  would be converted to imperial units (mils) and rounded up to the next mil.

 

I am used to designing in metric units while the website is specified in imperial units. Is there a conversion chart I can refer to ?


When requesting an online quote, the quote form can handle mm units as well as inches for dimensions.

 

How do I specify internal cutouts/milling in my design?


All internal cutouts/slots/milling should be specified on the same layer is the board outline. The the minimum routable slot size is 32 mils. During order time, please state this requirement in the "Special Request" section so that our CAM engineers is aware of it. This is not something we encounter often - so there are chances we may overlook it. Make sure it's known to us.

Description:

 

1. Copper foil substrate (Copper Film)
Copper foil: basically divided into two kinds of electrolytic copper and rolled copper common thickness 1oz 1/2oz and 1/3 oz
Substrate film: a common thickness of the 1mil with 1/2mil two kinds.
Glue (adhesive): thickness according to customer requirements.

 

2. Cover film protection film (Cover Film)
Cover film protection film: surface insulation. The common thickness 1mil with 1/2mil.
Glue (adhesive): thickness according to customer requirements.
Adhesive buildup of foreign matter before pressing the shape from the paper: avoid; easy job.

 

3. Stiffener (PI Stiffener Film)
Stiffener: reinforcing the mechanical strength of the FPC, to facilitate the surface mounting job. Common thickness 3mil to 9mil.
Shape from the paper: to avoid foreign matter adhesive buildup Crimping before the.

 

4. EMI: electromagnetic shielding film, the protection circuit board line without interference from the outside world (a strong electromagnetic District or susceptible to interference zone).
 

 

Applications: 


1. Disk drives
Regardless of the hard disk, or diskette, is very dependent on FPC high softness and thickness of the 0.1 mm slim, read data finish quickly. Either a PC or NOTEBOOK.
