| I am in the process of picking a new resistor network for one of our new board. Since we are new to SMT i would like to get some opinions on networks. Currently we use one molded gullwing type network on our boards with no problems. Other than spac

Is the industry really moving toward unmarked chip resistors? I've been seeing a lot of unmarked 0603 resistors lately, and when I check the data sheets, all their photos are of marked parts, and they don't say anything about it.

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w

Pls. help. I�ve problem with non-wetting defect at capacitor termination. I have faced this problem at the 2 kinds of termination. One is chip capacitor 0603 that its outer termination surface composed with 100 Sn (Lead free) and another one is Sta

Cracked capacitors usually are not found at ICT. Unless the cap is completely cracked, the capacitance may not change much, and the usual failure mode is a leakage current. This is usually only seen in ESS type testing, when temperature and humidit

Sal, Silly question: Were the parts skewed before they went into the oven? I've chased down a few similar reflow problems in my lifetime, only to find out it was a pick and place problem. Wrong nozzle size, bad nozzle, feeder not advancing all

Thanks for your advise Now I don't found Non-wetting defect at TIN COATED 0603 after I had increased peak temp and Time above 183 C. At film caps, I still found Non-wetting in high rate at film chip size 2416. I using PANASONIC's part with identif

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

| Could use a little help here. Can anyone clarify to me the cause and fix of chip caps/resistors tombstoning following reflow? | | Any help would be appreciated. Thanks. | Most common reason is uneven heating where one side of the component ach
