Horizontal Process Equipment for DMT Although many DMTs fit easily into existing electroless copper lines, whether manual or automatic, and perform well in a vertical mode, DMT is becoming inextricably linked to horizontal processing in a conveyorized machine. Like so many inventions, necessity was its mother. Certain DMT processes are marginal in the vertical/basket mode, and handling each panel individually was the only solution.The advent of compact and inexpensive horizontal DMT equipment has been a catalyst.Although Atotech pioneered horizontal electroplating equipment with their Uniplate system, until the development of horizontal DMT machines it was not feasible to engineer a horizontal PTH machine. Now, however, for those who want only flash plating, or even full electroplating, the entire process both PTH and galvanic may be horizontal, conveyorized, and automated with the advantages of reduced chemical consumption; radically reduced use of rinse water; panel-to-panel uniformity, reliability, and quality; reduction in operating personnel; reduction of handling; a fully enclosed operating environment; and JIT delivery. Stackers/accumulators further minimize handling and optimize efficiency.
DMT Process Issues Anything brand new experiences some teething problems at the beginning, and DMT is no different. But most of the processes referred to in this chapter are in at least their second generation and some are already in their third, so there are no serious contraindications to the use of DMT. However, there are a few caveats: 1. Esoteric base material does not run well with all DMT. 2. Not all DMT performs as well in the vertical mode as in the horizontal. 3. Certain DMT is better suited to the rigors of multilayer production. 4. Some perform better than others with very small holes. 5. Some processes are cleaner than others. 6. Certain DMT is more sensitive than electroless copper to organic contamination in electrolytic copper plating.
DIRECT PLATING
7. Rinsing is important, and some DMT needs special rinsing. 8. Rework is simple in most DMT, but it can be abused, i.e., it changes the cost structure. 9. Quality assurance tools for DMT (how do you know that holes will plate void-free ) are being developed, but at the moment, the only absolutely certain method is to flash electroplate, because, unlike electroless copper, there is not much to see in the hole after DMT. 10. Some DMT analyses and operating controls are rudimentary. 30.1.9 DMT Process Summary Strong ecological and health reasons will drive the use of DMT for the manufacture of PTH boards. Since the cost of PTH metallization constitutes only 2 to 3 percent, at most, of the total process cost of a PCB, the direct saving resulting from DMT is very small. However, the fringe benefits of this technology are rather significant: water conservation, no noxious chemicals, minimal panel handling, reduced waste treatment, lower labor costs, fewer rejects, etc.
