MP3 players are destined for a demanding consumer market and cannot be compromised in any way. Code reading is an essential product-tracking procedure for printed circuit boards (PCBs) used in MP3 players, allowing manufacturers to protect themselves against costly recalls and product mix-ups, as well as allowing for damage control in the event of a problem. Sony’s Malaysian plant (Penang, Malaysia) had an issue with badly read codes, which resulted in high rejection rates that were costing the company money in terms of re-work and rejected units. When this code-reading system proved incapable of rising to the challenge, Sony began searching for a solution.
Measurement uncertainty is about how close your measurement is to reality. These days, “close enough for artillery” won’t cut it and neither will “a couple of tenths or so.”
As most of us pay attention to the largest players in the automotive industry, one smaller automotive manufacturer, in a largely ignored part of the world, is demonstrating that it is the company that bears watching.
The Quality Magazine Professional of the Year Award was started several years ago to recognize an individual who, during the course of his or her career, has made outstanding contributions to the quality profession.
Most discussions on the quality of surface finish revolve around the measure of roughness. Indeed, roughness is the most common measure of surface finish, and parameters such as average roughness (Ra) and mean roughness depth (Rz) are the most commonly specified. But the ways to measure a surface and the reasons for doing so go far beyond roughness.
The TroubleShooter LE, a handheld high-speed digital video camera, can record up to 500 frames per second and then play them back immediately on its built-in screen. Production and maintenance engineers can immediately see where problems are occurring and make appropriate adjustments to the production line.
Boulder Imaging, a systems integrator involved with machine vision, saved its customer money by switching camera sources for its machine vision system.
