Soldering

ACC offers various soldering techniques that are customized for the requirements of your product. 

Almost everything we do involves soldering, and quality soldering is fundamental to a quality printed circuit board.  In the following articles we will give you a brief discussion of the soldering processes offered by ACC.  Please click on the soldering process in which you are interested.  Photographs and video demonstrations are shown on the Equipment Page.

Reflow Soldering

Reflow Soldering is used for Surface-Mount Components.  Our twelve-zone Heller ovens are programmed to provide a custom solder profile for your printed circuit board.  This ensures that each component is heated to the correct temperature for proper solder joints. Either Lead-Free or Tin-Lead solder is available.

Wave Soldering

Wave Soldering is used primarily for Through-Hole Components.  We use an Electrovert machine for tin-lead solder and a Qualitek (JT) machine for lead-free solder.  These machines have pre-heaters that properly activate the flux and gently bring the components up to soldering temperatures to avoid thermal shock.  Both machines are equipped with chip waves to accommodate surface-mount components that are mounted on the bottom side of the board.  The entire printed circuit board skims across the surface of the solder wave. 

Selective Soldering

Selective Soldering is a variation on wave soldering.  In this case, however, the machine is programmed to take a small wave to selected areas of the board where wave soldering is required.  This machine is used when components that can't pass through liquid solder are mounted on the bottom of the board.  Both Lead-Free and Tin-Lead solder are available.

Robotic Soldering

Robotic Soldering is similar to hand soldering in that it uses a solder tip and flux-core solder.  The machine is computer controlled and can be programmed to apply the proper amount of heat to each solder joint.  If a component is being soldered to a ground plane, the dwell time is extended to bring the solder pad and component lead to the proper temperature for soldering.  If the component is being soldered to a small copper trace, the dwell time is shorter.  Lead-Free and Tin-Lead solder are available.

Hand Soldering

Hand Soldering is still available and is sometimes the best way to get the job done.  All ACC production associates are trained and certified for IPC soldering standards.  Again, Lead-Free or Tin-Lead solder is available.
