Three common sense related to PCBA

PCBA engineers must know Component package

Nowadays, most of electronic component has been standardized size.
And the standardizing component package makes it easier for PCBA engineers.
Due to the size of component package is known, just consider other factors in PCBA design.
4MCPCB experts also note that there were still plenty of packages out standard.
This means you also consider the un-standardizing component package during PCBA design.

The Component Package that 4MCPCB accept
We accept pets in Reels, Cut Tape, Tube & Tray, Loose Parts and Bulk.
If you have other component package, please contact with us.

The PCBA engineer must know Component Size

If you are a new PCBA engineer, you may confuse about component size.
In fact, the PCBA component size is the simplest definition.
Because most of component size data can get from internet.
Here we introduce three basic component size.
Passive Component: we can accept components as small as 01005, 0201,0402.
BGA: We have the ability to handle BGA of 0.25mm pitch with X-ray testing.
Fine Pitch Parts: we can assemble 0.25mm fine pitch parts.

The PCBA engineers must know Board Dimension

The board dimensions of PCBA are the basic parameter.
Due to all of our PCBA are using automatic machine.
This means that the PCBA board dimension must design right or can not use automotive machine produce.
Here we list two main board dimensions of 4MCPCB accept.
Min Board Size: 50mm x 100mm (Boards smaller than this size need to be penalized)
Max Board Size: 250mm x 500mm
