Effects of Assebly Process Variables on Voiding at a Thermal Interface.

The present work offers a discussion and a first case study to identify and illustrate voiding mechanisms for a particular TIM between a heat spreader and the back of a flip chip. Pronounced differences were observed between stencil printing and dispensing in terms of initial void formation ...

THE EFFECT OF VACUUM REFLOW PROCESSING ON SOLDER JOINT VOIDING AND THERMAL FATIGUE RELIABILITY

A test program was developed to evaluate the effectiveness of vacuum reflow processing on solder joint voiding and subsequent thermal cycling performance. Area array package test vehicles were assembled using conventional reflow processing and a solder paste that generated substantial ...

Controlling Voiding Mechanisms in the Reflow Soldering Process

While a significant level of voiding can be tolerated in solder joints where electrical conductivity is the main requirement, voiding at any level severely compromises thermal conductivity. For example, in LED lighting modules effective conduction of heat through the 1st level die ...

Effect Of Voids On Thermo-Mechanical Reliability of Solder Joints

Despite being a continuous subject of discussion, the existence of voids and their effect on solder joint reliability has always been controversial. In this work we revisit previous works on the various types of voids, their origins and their effect on thermo-mechanical properties of solder ...

Operation of a Vacuum Reflow Oven with Void Reduction Data

Voids affect the thermal characteristics and mechanical properties of a solder joint, thereby affecting the reliability of the solder interconnect. The automotive sector in particular is requiring the mitigation of solder voids in various electronic control modules to the minimum possible ...

SM421 crash issue -- we have 3 SM421 in our production line. One of them has started showing an error while booting up. "Failed to Initialize visual code". I have tried swapping the hard disk image with a backup image however once I load a program and move onto finish and then download I get a popup saying " error with windows, need to shutdown and reboot your system". Once I click ok the system shuts down and then it goes back to the initial error. The entire cycle keeps on repeating even after trying different programs. Can someone please advice how do I get out of this predicament. I have a feeling it could be related to the Samsung boot up s/w

DEK Horizon -- So we run a DEK horizon, thats been fairly reliable. The other day before I came in, my operator said something burned up and it no longer worked. I swapped out power supply, pnoz, 2 of the relays and the pilz P1HZ/2. While this got me past my initial pneumatic power error and a software reinstall got past the winNT Dr watson errors, after initializing the machine, the DEK program just sits there, nothing moves. Eventually it'll throw an error, but so far it seems random. Ive gotten rising table error, lid bolt error, and camera failed to initialize errors. I have swapped out the MM cards from another machine and no dice. If I go into diagnostics before initializing it, I get a (I don't remember the exact wording) power failure msg. I can reinitialize and pick a different diagnostic module, and I get the same power error. Any suggestions? Im not super familiar with the inner workings, so if you skip the abbreviations id appreciate it. Thanks
