These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

Suggestions please... I have to place a number of 1206 chip resistor arrays on the bottom side of my PCB for wave soldering. The device consists of 4 x 0603 resistors in a 1206 package. The device is available with either concave or convex terminati

Rob: What was driving the uBGA bridging? On your arrays: * I doubt that your supplier would be pleased that you are wave soldering these pups. If you insist, present leads to the wave on opposite sides of the package at the same time. Is this an

Quick question for Dave, Out of curiosity, why concave? I ask because we are soldering RNETs that come in either style and have not payed much attention to this. Russ

Thanks, Dave appreciate the info. One of my trains of thought was leading to the convex because I thought that having the "bump" would allow for easier wave soldering? I did look at some data we had and did find you to be correct, the concave hav

Dave, We are using Kester Easy Profile 256 No clean Sn62Pb36Ag02. The oven itself is a Dima SMRO-0252 which is a short oven, it has 13" of preheat, 13.5" of soak, 6.25" of reflow, and 10" of cooling on the way out of the oven. We are soldering multi
