Digicom Electronics, a technology and quality-driven electronics manufacturing services company, introduces its new Diamond Track Cleaning Process. This process uses a proprietary combination of chemicals, temperature, wash cycles, timing, and equipment that results in printed circuit boards with superior quality and cleanliness. Independent tests show that the boards test 75% cleaner than the IPC’s highest level of clean. In addition, a recent lab analysis for ion contamination found zero ion contamination on assembled boards. This level of cleaning eliminates failures caused by board contamination. „There is a gap in the market caused by new technologies that make it more difficult to ensure circuit board integrity,“ explained Mo Ohady, general manager. „Today’s chemistries in fluxes and solder, plus the closeness of components, make cleaning more difficult. Many failures are due to boards that retain contaminants from the manufacturing process. It’s not enough to put the boards through a wash cycle. It takes a special combination of chemicals, temperature, wash cycles, and timing to get the boards really clean.“
The cleaning process is repeatable, reliable, and uses an advanced in-line cleaning system to increase speed and throughput. All boards are routinely run through the system both prior to and after the assembly process. This ensures that the soldering process is not compromised by any contaminates from the board fabrication process and the boards are completely clean of any remaining chemicals from soldering. With the unique Diamond Track Cleaning, products are less susceptible to corrosion-induced failures, thus reducing the need for maintenance or repair. The cost savings to the customers, especially those with military, aerospace and medical device applications, are considerable. The Diamond Track Cleaning Process is completely green. De-ionized water from polishing tanks is used and recycled. Filters catch the solids while powerful blowers ensure that harsh chemicals don’t migrate passed the holding tank. Clear windows on the equipment enable the operator to monitor the entire process. A refractometer checks the stability of the mix in the tank to see that it’s not compromised. The discharged liquid is completely environmentally friendly.
