Identifying the Cause of Tool and Die Failure
Jan 06, 2016· Machining problems are a common cause of tool and die failures It is generally best to avoid machining directly to the finish size unless prehardened die steels are used Obtaining perfect control of surface chemistry and size during heat treatment is difficult Thus, some final grinding is usually needed after heat treatmentIntroduction To Die & Wafer Products SBOA147 factors, such as the cost of the substrate and efficiency of the rework process machine, or process in which TI components or services are used Information anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that mightDie & Wafer Overview Texas Instruments
The Ultimate Guide to Wafer Sort AnySilicon
Jan 25, 2017· Wafer sort’s main purpose is to identify the nonfunctional dies and thereby avoiding assembly of those dies into packages In many cases, wafer sort is a simple and quick test that focuses on a few electrical parameters that are most likely to fail Wafer testing is performed during IC production on every wafer and every silicon dieThe wafer saw process cuts the individual die from the wafer leaving the die on the backing tape The wafer saw equipment consists of automated handling equipment, saw blade, and an image recognition system The image recognition system maps the wafer surface to identify the areas to be cut, known as the saw street DI Water is dispensed onSemiconductor Packaging Assembly Technology

The Most Common Accidents in the Mining Industry
Jan 14, 2019· The yearly average in coal mining decreased to 30 fatalities from 20012005, though 60 to 70 miners still die each year in the US coal and noncoal mining industry The most common accidents occurring in the mining industry are the result of poisonous or explosive gases or mishaps relating to the use of explosives for blasting operationsThank you it is direct simple, it will help many to understand common failure types If you add something about mechanism of failure and how to prevent their reoccurrences it will be great Reply Christoffer Wesley says June 4, 2018 at 11:42 am Hi, always nice with some “back to Basics” articles!Failure Modes: Understand the 5 most common failure types
