Failure Analysis – Using Ion Chromatography And Ion Chromatography/Mass Spec (IC/MS)

Since the 1980s the electronics industry has utilized ion chromatography (IC) analysis to understand the relationship of ions, and some organics, to product reliability. From component and board fabrication to complete electronic assemblies and their end-use environment, IC analysis has been the de facto method for evaluating ionic cleanliness of electronic hardware.

Column Properties That Make An Impact On Ion Chromatography

For the separation of ionic species, ion chromatography (IC), a type of liquid chromatography, is the method of choice. The most critical component of this technique is the separation column, which is selected based on factors that include the specific analytes of interest, the sample type and the required detection levels. This article outlines the column parameters that impact the separation of charged species in solution using ion-exchange chromatography and the developments that have continued to redefine what is possible with an IC system.

Pick and Place Startup - LQPF100 bridging issues -- I work for a company that, up until now, has done everything using through-hole components. This has been fine for years, but we have been pushed into the world of surface mount manufacturing by a new product that is far cheaper and faster to manufacture this way. Our setup consists of a manual stencil printer, CHMT36VA desktop pick and place machine, and a DDM Novastar GF-B-HT batch reflow oven. The paste we are using is ChipQuik TS391AX500C.

Universal GSM Blue Label Feeder (24V) -- Looking to repurpose some older 32mm GSM Blue Label feeders for a custom application. These feeders are the 24V type and not 42V. Does anyone have any information on connecting to and communicating with the feeder outside of a GSM machine or setup cart?
