IR receivers in pin-in-paste side-view holder lower assembly costs and increase reliability

Vishay Intertechnology has broadened its optoelectronics portfolio with the introduction of a new side-view metal holder for the company's TSOP33xxx and TSOP53xxx series of miniature Minimold IR receiver modules for IR remote control applications. Taking advantage of the receivers' support for IR reflow soldering, the Vishay Semiconductors P1xP holder enables PiP soldering to reduce assembly costs and increase reliability. As designers continue to replace through-hole devices requiring wave soldering with higher-temperature equivalents, PiP technology has emerged as a new cost-effective method for mounting the components — together with surface-mount packages — via reflow soldering. In the PiP process, after components are positioned on the PCB, the entire board is soldered at once using only the reflow oven, eliminating the wave-soldering step for through-hole devices. This results in a more reliable solder process flow at a lower cost. The holder released today is available for PCBs with thicknesses from 1mm to 1.6mm. Featuring three-point, surface-mount solderable tabs, the P1xP reduces the number of automatic insertion points while improving co-linearity and grounding for better RF and EMI rejection. Dry-packed in stiff plastic trays for automatic pick-and-place assembly, the holders feature a large pick-and-place area and clips to securely hold the IR receiver module. For products such as televisions, set-top boxes, air conditioners, and high-end audio systems, the company’s Minimold devices provide high sensitivity with typical irradiance of 0.08 mW/m² at 0 degrees for the TSOP33xxx series and 0.12 mW/m² for the TSOP53xxx series. The Minimold package is also available with the proven "F" option for an enhanced optical filter against out-of-band optical noise, while TSOP53xxx series devices are highly resistant to RF interference. RoHS-compliant, halogen-free, and Vishay Green, the devices are also available in a top-view surface-mount version.
