Abstract:
A striped tape carrier for TAB includes a plurality of mounting parts. In the respective mounting parts, wiring patterns to bond electrodes of electronic components are formed. Each of exposure regions includes a predetermined number of mounting parts. On both sides of each of the exposure regions, alignment marks and identification marks are formed. The alignment marks are used for alignment during the exposure. The identification marks are used for specifying positions of the respective exposure regions on the tape carrier.
Abstract:
A resistor/capacitor identification detection (RCID) circuit may provide system level identification of hardware (e.g. circuit board ID) through a single pin interface, by identifying up to a specified number of more than two quantized RC time constant states by measuring the discharge and charge times of an external RC circuit coupled to the single pin. The RCID circuit may initiate the discharge followed by a charging of the external RC circuit. The signal developed at the signal pin may be provided to the input of a threshold detector, with the threshold set at a specified percentage of a supply voltage used for operating the RCID circuit. The digitized output of the threshold detector may be used to gate a counter, after having been filtered through an input glitch rejection filter. A resolution of the counter may be determined by a high frequency clock used for clocking the counter. The numeric values of the charge and discharge times may be stored in data registers comprised in the RCID circuit.

Abstract:
An identification code drawing method of drawing an identification code on a substrate includes: cleaning the substrate by using a cleaning unit; performing lyophobization for the substrate; discharging liquid droplets of functional liquid, into which particles of metal or metal oxide are dispersed, from nozzles of a first liquid droplet discharging head onto a region of the substrate having been subjected to the lyophobization, on the basis of liquid droplet discharge data for drawing the identification code; and heating the liquid droplets adhered on the substrate by using a heating unit or drying the liquid droplets adhered on the substrate by using a drying unit.
Abstract:
A method of assembling multiple electronic components to a circuit board includes securing one electronic component to the circuit board, then, creating an association between that electronic component and an environmental condition recorder. The method further includes recording data from the environmental condition recorder. The recorded data indicates exposure of the secured electronic component to an environmental condition over time. The method also includes determining, based on the stored data, whether the secured electronic component is suitable for exposure to conditions associated with securing a second electronic component to the circuit board.
Abstract:
A marking system or identification code for a flexible circuit or cable is disclosed. The system provides individual tracking for flexible circuits or cables assembled in data storage systems. As described, the flexible circuit or cable includes an identification code or marking on a flexible substrate for providing individual tracking for a flexible circuit or cable of a data storage device.
Abstract:
The invention relates to preparations, a component tape and a component tape reel for marking printed circuit boards with respective unique identification codes. Carriers with respective unique identification codes printed thereon are packaged and provided in such way that the carriers can be mounted on respective circuit boards by an automated component mounting process. Thus, the invention enables a surface mount placement system to pick the carriers for placement on respective circuit boards, thereby marking the circuit boards with respective unique identification codes in a fully automated manner.
Abstract:
A method for individualised marking of electronic components in electronics manufacture, such as circuit boards. On the photosensitive surface required for manufacturing the blanks is exposed, on each blank, a machine-readable pattern, which is subsequently used in the manufacture of the product itself, for individualising the blanks in question.
