Electronics assembly was traditionally labor intensive.  These days everything except specialty circuits can be fabricated all or mostly by machine, making most circuit assemblies much more economical to build.  But in those special cases when you need precision handwork, there’s no substitute.  And when you need it, DCS has it.

  • Cleanliness testing

  • X-ray and optical inspection

Precision handwork

  • Complex electro-optical or electro-mechanical assembly
  • Custom modifications
  • Circuit board repair
  • BGA re-balling

 

Automated assembly

All the usual stuff.  We grew up on thru-hole, don’t have anything against it and kept the tooling.  But we have moved on with the times.  High density surface mount is the future and DCS is along for the ride.  We can place passives as small as 0201 and pretty much any IC package. 
And for those parts that can’t be reflowed it’s a quick run through the solder wave.

  • SMT, Through Hole or Mixed
  • Hand placement and hand soldering
  • Lead or RoHS soldering
  • No-clean fluxed process available for non-washable parts

We are have integrated solutions for small prototype to large production runs and

hand assembly.

  • X-ray inspection

  • SMT down to 0201

Printed circuit board (PCB)

Bare-board test - Boards with no components installed are usually bare-board tested for "shorts" and "opens".

Solder resist application - Areas that should not be soldered may be covered with solder resist (solder mask).

Lamination - Cut through a SDRAM-module, a multi-layer PCB. Note the via, visible as a bright copper-colored band running between the top and bottom layers of the board. Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time.
