Surface Mount Assembly Using Machinery (pick and place machine)

Use of leaded or through hole parts have become rarer, and are now discouraged by assemblers. It is far more efficient to machine assemble an electronic circuit if it is completely populated with surface mounted components. Leaded parts are laborious to fit. They need lead trimming and bending, hand placement, further trimming and hand soldering. SMD parts are simply machine picked and placed from a reel. Parts such as connectors which have not been available in SMD form can now be machine placed.

The latest model SMD placement machines are capable of placing a wide variety of part sizes from the smallest type 1005 SMD parts (dimension 1.0 mm x 0.05 mm) up to large SMD connectors (dimension 30 mm x 10 mm). There are now very few parts not available in SMD form and for which an SMD placement machine cannot handle the placement. Saica electronics is equipped with such machines.

With careful use of parts, it is quite practical to design products which are completed in one pass down an automatic SMD assembly line without any extra hand assembly work other than to snap the circuit board into a moulded enclosure. Get a PCB assembly quote today!

Surface Mount Soldering

A key process in surface mount assembly is the design of the solder paste stencil. It is paramount that the quantity of solder paste deposited on each pad is repeatable and precisely controlled. We consider this to be so important that we precision cut our stainless steel stencils by laser using our own in-house industry standard laser cutting machine. Modifications and improvements to production stencils can be made at low cost within hours as and when required, minimising delays and waiting time.
