Description
QFP Probing Adapters
Ironwood’s QFP Probing Adapters, or “Carrier Adapters”, are two-piece systems that allow probing and socketing of QFP devices. The socketed probe board plugs into an SMT emulator base, or “foot”, that is soldered to the target board. The QFP Clip allows probing of an SMT mounted QFP IC.
Ironwood’s QFP Carrier Adapters are two-piece systems that allow for the probing and socketing of QFP devices. The bottom assembly is a surface mount foot (emulating the QFP package) that solders onto the target system’s QFP lands. The foot presents an array of gold plated pins to the upper probing assembly, which “carries” the IC device and presents gold plated test point pins for each signal. The upper assembly is available with a ZIF socket (-Z parts) or less expensive surface mount lands (-S parts) as in the drawing to the right.
These two piece QFP probing adapter assemblies are sold in the on-line catalog as a single package, however, the surface mount foot is also offered separately as the SF- part number described in the “Compatible Part” column.
The QFP Clip allows probing of individual pins on a QFP IC soldered directly to SMT pads. A fastener is attached to the top of the IC and the QFP clips makes contact to each of the QFP pins with spring pins. The 2.54mm pitch header pins are then connected to each pin on the QFP to allow logic analysis or scope probing for all pins. The header pins and spring pins are gold plated for highest reliability connection.
