Pcb Part Numbering System
Engineering unit full power output from 55 c to 85 c case temp linearly derates to zero at 115 c.
Pcb part numbering system. B pcba part number this is different and there may be more than one pcba part number that uses the same pcb. In the video we talk about the basi. 24 hours burn in 25 c test data only. It s important to note that this is not guaranteed to be consistent with the pcb.
A part numbering system is used within a manufacturing company as a way for individuals and departments to identify and track parts. Often manufacturers will use either an intelligent part numbering or non intelligent part numbering scheme. Categorizing parts in a standardized way can create efficiencies in many manufacturing processes. Eus are used for evaluation in lab or non flight applications.
For example we may omit some components and not others. 24 hours burn in 25 c test data only. I was wondering what drawing numbering system you guys use for the schematics and pcbs. Since pcbs are manifested using the same manifest as rcra hazardous waste all changes to part 761 are being implemented by pcb waste handlers and generators.
It seems that the first three numbers define the document type then comes the project number and then the revision. Using this part numbering system a resistor could be assigned part number 000416782. Intelligent also referred to as significant the part number contains descriptive and informative details that provide significant information about the part. It is always recommended to use the number on the sticker instead of the number stamped on the board when ordering a pcb.
Pcb waste handlers and generators must also adhere to the more recent rcra hazardous waste manifest regulations while still accounting for certain unique pcb manifest regulations. Industrial grade unit full power output from 55 c to 85 c case temp linearly derates to zero at 115 c. For instance i looked at an altera fpga development board and they seem to be using the system in the attachment. The part numbering system must accommodate high volume users people who work with hundreds or even thousands of part numbers each week.
With part number systems of multiple vendors in place we will not contribute to tidiness in our own numbering system.
