2、y Leaded Package Thermal Measurements”. This standard covers the design of printed circuit boards (PCBs) used in the thermal characterization of Pin Grid Array (PGA) packages. It is intended to be used in conjunction with the JESD51 series of standards that cover the test methods and test environmen
3、ts. JESD51-11 was developed to give a figure-of-merit of thermal performance that allows for accurate comparisons of packages from different suppliers. It can be used to give a first order approximation of system performance and, in conjunction with the other JESD51 PCB standards, allows for compari
4、sons of the various package families. JESD51-11 helps complete the series of standards that now covers virtually all of the major package families. JESD51-11 was developed by the JC-15.1 Subcommittee on Thermal Characterization under the chairmanship of Bruce Guenin of Amkor Technologies and the aut
5、horship of Mr. Paul Hundt of Texas Instruments.

19、st board suggestion 8JEDEC Standard No. 51-11-ii-ForewordThe measurement of the junction-to-ambient (RJA) thermal characteristics of an integrated circuit (IC)has historically been carried out using a number of test fixturing methods. The most prominent method isthe soldering of the packaged devices
20、 to a printed circuit board (PCB). The characteristics of the testPCBs can have a dramatic (60%) impact on the measured RJA. Due to this wide variability, it isdesirable to have an industry-wide standard for the design of PCB test boards to minimize discrepanciesin measured values between companies.
21、To obtain consistent measurements of RJAfrom one company to the next, the test PCB geometry andtrace layout must be completely specified for each package geometry tested. Such a completespecification would limit the flexibility of user companies who would like to design test boards for theirindividu
22、al needs. Thus, one characteristic of a test board specification is to allow some variability ofPCB test board design while minimizing measurement variability.This specification is intended for use with the thermal measurements and modeling specificationsgrouped under JEDEC EIA/JESD 51, 1.
