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