Factory automation is a cost-effective and resource-efficient solution to many complex microelectronic assembly challenges. Form factor and presentation of materials such as packages, substrates and components are simplified through implementation of industry standards such as SMEMA, JEDEC and SEMI, among others. Unique, custom and application-specific presentation and assembly methods may also be applied when necessary. Throughput and yield improvements are achieved by reducing employee contact with the assembly process. Precision robotic control combined with automated production line data monitoring reduces process variation and virtually eliminates assembly errors. Identification and tracking of assembly processes, materials and production quality improve overall facility efficiency.
What is Your Objective in Factory Automation?
- Do you need to build a million units per month?
In-line Assembly Solution is preferable
- Do you need flexibility to build a small combination
of products in medium volumes?
Islands of Automation may be preferable

Islands of Automation —individual processes such as component-attach or wire bond are performed within independent automated work cells; the packages are fed automatically through the work cells via a system of process carriers (boats) and magazines. The value of islands of automation is intended to be realized through greater production flexibility and faster product changeover.
- Process operations such as die-bond and wire-bond run independently of the whole production line
- Enables greater product changeover flexibility
- In-line buffers are not required
- In-line buffers are not required
- Requires less integration time and effort than an inline system
- Line throughput is dependent upon scheduling separate operations
- May require more labor to support independent work cells
- Requires more input and output process carriers and handlers
In-Line Assembly Systems—Packages are fed automatically through the production line via a system of process carriers and magazines in the same way islands of automation are – however, the production line may require buffers to balance throughput and the production rate is fixed at the rate of the slowest process in the line. The value of an inline system is intended to be realized through high-volume, low-mix assembly of a single type of product with minimal or no product changeover and greater yield due to reduced operator contact with the product and materials.
- May require less labor to operate than islands of automation
- Line throughput is not dependent upon scheduling separate operations
- Process operations such as die-bond and wire-bond run together as a whole production line
- Fixed production rate allows for more accurate production planning, and potentially higher throughput
- Reduces product changeover flexibility
- In-line buffers are frequently required to balance slow and fast operations which can add cost
- Requires more up-front integration engineering time and effort than islands of automation
