Description
QFN-MLF Surface Mount Emulator Bases
Patented QFN SMT Feet provide a reliable method for interconnecting to QFN pads on the target PCB. These high performance adapters have the same pad configuration as the QFN IC being emulated and a female socket array to which various adapters can be plugged. The SF-QFN/MLF small footprint Surface Mount Package Emulator Feet for all sizes of QFN/MLF, pitch ranging from 0 .4mm to 0.65 and many body sizes. These devices use patented technology to achieve a reliable and chip size SMT QFN/MLF adapter. The SF-QFN/MLF has pads on the bottom that precisely match the pin layout for the QFN/MLF package including the E-pad or heat sink pad in the center of the pattern. This allows connection to a QFN/MLF land pattern of target board and provide a set of interconnects available for probing or connecting to another assembly. The user simply solders the SF-QFN/MLF adapter using the same solder reflow and attachment methods used for a QFN/MLF IC. The SF-QFN/MLF adapter is the same size as the QFN/MLF IC in the XY dimension and only 3.3 mm high. The top of the adapter after being attached to the target consists of female, machined socket pins with complete gold plating for maximum reliability.
