Capacitor Array Capacitor Array (IPC) BENEFITS OF USING CAPACITOR ARRAYS AVX capacitor arrays offer designers the opportunity to For high volume users of cap arrays using the very latest lower placement costs, increase assembly line output placement equipment capable of placing 10 components per through lower component count per board and to reduce second, the increase in throughput can be very significant and real estate requirements. can have the overall effect of reducing the number of place- ment machines required to mount components: Reduced Costs Placement costs are greatly reduced by effectively placing If 120 million 2-element arrays or 40 million 4-element arrays one device instead of four or two. This results in increased were placed in a year, the requirement for placement throughput and translates into savings on machine time. equipment would be reduced by one machine. Inventory levels are lowered and further savings are made During a 20Hr operational day a machine places 720K on solder materials, etc. components. Over a working year of 167 days the machine Space Saving can place approximately 120 million. If 2-element arrays are Space savings can be quite dramatic when compared to mounted instead of discrete components, then the number the use of discrete chip capacitors. As an example, the of placements is reduced by a factor of two and in the 0508 4-element array offers a space reduction of >40% vs. scenario where 120 million 2-element arrays are placed there 4 x 0402 discrete capacitors and of >70% vs. 4 x 0603 is a saving of one pick and place machine. discrete capacitors. (This calculation is dependent on the Smaller volume users can also benefit from replacing spacing of the discrete components.) discrete components with arrays. The total number of place- ments is reduced thus creating spare capacity on placement Increased Throughput machines. This in turn generates the opportunity to increase Assuming that there are 220 passive components placed in a overall production output without further investment in new mobile phone: equipment. A reduction in the passive count to 200 (by replacing discrete components with arrays) results in an increase in throughput of approximately 9%. A reduction of 40 placements increases throughput by 18%.
