A tight tolerance machine isn't necessarily a specific machine type. Rather, it's any machine capable of producing parts with precision tolerances. This means minimal variation in the final dimensions of the part. These cutting-edge tools are meticulously engineered to achieve exceptionally precise measurements within minuscule margins. This is accomplished with CNC, or computer numerical control, a manufacturing method that automates the movement of a machine and optimizes for precision. With technology and advanced techniques, these machines ensure that every component meets exact specifications, guaranteeing unparalleled accuracy in manufacturing processes.

Pentium-class portables present significant packaging problems. The heat generated inside a notebook not only reduces microprocessor reliability, but the reliability of peripheries such as hard drives and video chips. Although the processor is the primary heat-generating source, it isn’t always the component least tolerant of temperature...

This book is a compilation of many articles I have published on the subjects of cleaning, reliability, and cleanliness testing. Throughout these articles, I promote a common mantra: Clean is better than dirty. Less contamination is better than more contamination. Some assemblies can tolerate more contamination; others, less.

Semiconductor manufacturing is characterized by very complex process flows made up of individual process steps, many of which are built to very close tolerances. Furthermore, there are complex interactions in these process flows, whereby each process step can affect many other steps, and each final device parameter might be determined by the results from many inputs...

The high level of current interest in embedded passives in printed circuit boards is driven by the tremendous pressure to pack more circuitry into smaller spaces. However, adoption has been limited due to design, prototyping and infrastructure issues, as well as the stability and tolerances necessary for widespread replacement of discretes. The focus of this work has been to develop a polymer thick film resistor technology to incorporate reliable organic resistors inside printed wiring boards using standard PWB processing.

We strive to produce quality parts for customers around the world looking for laser cutting precision. We are able to produce quality machined parts to the specifications provided by customers because of the strong quality system. Precision parts with tight laser cut hole tolerances cannot be done without our quality department. Supplying quality machined parts defines who we are and laser micromachining wouldn't be possible without it.

A-Laser enters the aerospace world with laser cutting services that continue to exceed performance expectations. The modern aerospace industry has strict tolerance requirements and A-Laser is prepared to meet those needs. For example, modern aerospace design dictates anywhere from dozens to millions of precise holes and channels. These must vary in thickness, diameters, and geometries. A-Laser is prepared to meet these requirements and we do so with faster, more versatile, more consistent and cost-effective tools.

As silicon technology advances to enable higher density ASICs, the core logic voltage decreases. The lower voltage, in combination with higher current requirements, requires tighter tolerances on the power supplies. The control of the power supplies from the PCB to the die is the subject of this study. A frequency sweep simulation using typical bypass values shows that a discrete package capacitor is not a significant factor in reducing the chip core power supply fluctuation. A small voltage boost at the PCB supply can provide a more economical solution to managing the device supplies.

Water soluble lead-free solder paste is widely used in today’s SMT processes, but the industry is slowly moving away from water soluble solder pastes in favor of no-clean solder pastes. This shift in usage of solder paste is driven by an effort to eliminate the water wash process. Some components cannot tolerate water wash and elimination of water washing streamlines the SMT process. Despite this shift, certain applications lend themselves to the use of water soluble solder paste.This paper details the research and development of a new water soluble lead-free solder paste which improves on the performance characteristics of existing technologies.

How to protect your PCB from moisture related damage? J-STD-033 put forward stricter regulation on the MSD exposure environment,when the exposure time exceed the tolerated,the moisture will penetrate into electronics,Moreover, the newest RoHS regulation will rise soldering temperature,the sudden high temperature will lead to expansion and cracking on electronic components. In order to decrease the moisture defect on PCB for the manufacturers in China,Climatest Symor® begin to concentrated on electronic dry cabinet R&D since early 1990s,we specialize in handling temperature and humidity for 20 years,and we provide best solution for PCB storage.
