We currently still build a fair amount of boards with through hole parts. These parts are placed by hand using kits, so there is always the "human" factor that tends to play into the root cause of the failure mode. Has anyone seen, heard of a method to improve hand placement of through hole parts?

Universal Sequencer, VCD, Radial, or Unimod(DIP installer) machines! We only still have and run our Universal/Berg pinning machine. I can't say they will work any better than humans do as humans will have to run and maintain them though. We did get great quality from ours!

Contact Systems cs400e

It's a semiautomatic thru hole machine that incorporates hand placement with a machine cut and clinch, was (probably still is) the benchmark in the industry.

Certainly, machinery provides better quality for repetitive tasks than manual methods. In looking to improve the quality of manual methods, there are things that can be done. Some of those things have been discussed in earlier threads here on SMTnet, for instance: http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=12443

Dilbert is correct. The CS-400E machine is the machine of choice. The component insertions are light guided, the components are automatically presented to the operator and the leads are automatically cut and clinched at programmable lead length and angle making it the perfect solution for mixed technology assembly. The machine will eliminate quality problems associated with wrong part, wrong orientation, missing part or parts lifted during wave solder. Also, because of the cut and clinch, lead forming is greatly simplified and lead trimming after wave solder is eliminated (which is known to cause solder joint fratures). The machines are manufactured by Versatec who acquired the assets of Contact Systems in September 2009. For more information got to http://www.versatecsolutions.com

Hi Dave, The short answer is "it doesn't". The mascot is simply a light guided assembly system. The major difference is the CS-400E machine has the fully programmable cut and clinch unit doing it's thing under the board while it is being assembled. With the mascot system component prep is much more involved and components will still fall out or lift during wave solder process. And with the mascot systems you still need to trim leads after wave solder also which is known to fracture solder joints and is simply not allowed in high reliability assemblies. The CS-400E eliminates costly lead prep and trimming and enhances quality so the ROI for such a machine is quite fast. --Greg--
