Furthermore, we are capable of assembling BGAs to Micro BGAs, Leadless components, Package on Package, High Density connectors, 0201 Package or big parts, Fine pitch components (pitch up to 8 mils) in addition to user detailed specifications on receipt of requisite set of files. 

To begin with SMT assembling, Shenzhen Grande generally accepts file in Gerber RS-274X, RS-274D for Design for Manufacturability (DFM) checking, Bill-of-Material (BOM) in the excel format so as to procure and verify the components, SMT programming file (Pick and Place file) etc. along with the various parts provided by the client. 

While sending the components to Shenzhen Grande, customer has to provide a separate packing for each different type of components with clear indications as to part number, value, reference designators according to the given BOM.

We use modern techniques such as X-Ray inspection for Leadless & BGA components to check the joint soldering. Automatic Optical Inspection (AOI) is used for verification of solder joints, component placement and orientation, etc. which further decides the cost and turn time for small quantity SMT assembling.
