Testing Services | |||
Your choices are... | |||
Agency Compliance Testing | Agency compliance testing certifies that products meet the safety and quality requirements of one or more agencies. | ||
Analytical Laboratory Testing | Vendors provide analytical services to assist in quality control, process monitoring, failure investigation, and research and development. | ||
Automated Optical Inspection | Computer-based, automated optical inspection analyzes an image of an in-process or completed PCB and locates defects such as broken traces, excess copper or solder, etching problems, and the misregistration of holes to the circuit pattern. | ||
Environmental Testing | Environmental testing is a procedure that simulates the environmental conditions to which a product may be exposed. Temperature, humidity, and vibration tests are some examples. | ||
Functional Testing | Functional testing is a procedure in which an assembly's overall operational characteristics are tested by simulating normal function. | ||
In-circuit Testing | In-circuit testing (ICT) is a procedure in which the circuit nodes of an assembly are accessed by pin-type probes to test individual components within the circuit. | ||
X-Ray Testing | X-Ray testing is a non-destructive technique that provides a thorough analysis of varying densities. Inspection of assemblies can be performed with submicron defect recognition. | ||
Other | Other unlisted, specialized, or proprietary testing services. | ||

Manufacturing | |||
Your choices are... | |||
Printed Circuit Board Assembly | Vendors provide printed circuit board (PCB) assembly services. | ||
Flexible Printed Circuit Board Assembly | Vendors are capable of working with flexible PCBs (as opposed to rigid boards). | ||
Rigid-Flexible Printed Circuit Board Assembly | Vendors can populate rigid-flexible PCBs. These are rigid boards with flexible interconnects. | ||
Microelectronic, Flip Chip | Flip chips are integrated circuits (ICs) that use a specific number of bumps to provide electrical and mechanical interconnections. Flip chips are designed for facedown mounting. | ||
Microelectronic, Chip On Board | Chi-on-board (COB) technology bonds bare dies to boards or substrates. Wire bond connections are made from board to die. | ||
Optoelectronic Assembly | Vendors assemble devices that function as electrical-to-optical or optical-to-electrical transducers. They also assemble instruments that include these devices. Examples of optoelectronic devices include light emitting diodes (LEDs), injection laser diodes, and photodiodes that are used regularly in optical fiber communications. | ||
RF / Wireless Assembly | Vendors assemble devices that function as RF or wireless transmitters, receivers or transceivers. They also assemble instruments that include these devices. Examples of RF and wireless devices include radio frequency identification devices (RFIDs), telecommunication devices, and other wireless devices that are used regularly in telecommunications and wireless data transfer systems. | ||
Through Hole Assembly | Through hole technology (THT) mounts components on a PCB by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. | ||
Surface Mount Assembly | Surface mount technology (SMT) adds components to a PCB by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads. Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board. Surface mounted components are usually smaller than equivalent through-hole leaded devices and, in some cases, are also less expensive. | ||
System Assembly | Vendors assemble populated board into larger assemblies. | ||
Other | Other unlisted, specialized, or proprietary design process. | ||
