Final Assembly

Category: Special Processing

Description: -- Final Assemby consists of processes that must be performed by hand, such as positioning hardware parts, installing jumper wires, and staking those wires.

Major Cost Drivers – Final Assembly

// Process Time for final assembly manual processes.

Process Time = Final Assembly Install Process Time + Wire Install Process Time

Final Assembly Install Process Time = (Final Assembly Align Time* Final Assembly Quantity) + Hardware Install Time

Final Assembly Quantity = (PSO)

Final Assembly AlignTime = (Machine variable)

Hardware Install Time = Hardware Stackup Locations* Hardware Stackup Install Time

Hardware Stackup Locations = (PSO)

Hardware Stackup InstallTime = (Machine variable)

//Jumper wire installation. Note: One end will be soldered and the other end will be assembled in hardware stackup.

Wire Install Process Time = ((Jumper Wire Cut Time + Jumper Wire Strip Time + Jumper Wire Solder Time)* Jumper Wire Quantity) + Jumper Wire Staking Time + Jumper Wire Curing Time

Jumper Wire Cut Time = (Machine variable)

Jumper Wire Quantity = (PSO)

Jumper Wire Strip Time = (Machine variable)

Jumper Wire Solder Time = (Machine variable)

Jumper Wire Staking Time = (Staking Mix Time /Batch Size) + (Jumper Wire Staking Time * Jumper Wire Staking Locations) //If “Is Jumper Wire Staking Required” = true

Is Jumper Wire Staking Required = (PSO)

Jumper Wire Staking Time = (Machine variable)

Staking Mix Time = (Machine variable)

Jumper Wire Staking Locations = (PSO)

Jumper Wire Curing Time = ((Load Time + Oven Time)/Batch Size) //If “Is Jumper Wire Staking Required” = true

Load Time = Oven Load Time + Oven Unload Time

Oven Load Time = (Machine variable)

Oven Unload Time = (Machine variable)

Oven Time = (Machine variable) * SEC_PER_HR
