It’s not pretty out there. Companies have spent fortunes on ERP software and implementation only to find that business performance has not improved at all. These large investments and negative ROIs have created a whirlpool of controversy, rampant company politics and even a number of lawsuits. The trade press has reported many negative ERP stories, and even annual reports have pointed the finger at ERP for lower-than-expected earnings. For some, this has created a higher level of fear about making a big ERP mistake...

As change is inevitable, therefore so is obsolescence. In the electronics sector, stocks of components used in subassemblies will eventually run out, no surprise there! However on many occasions, particularly in the often long product life cycles associated with the traditional UK OEM’s in the industrial, military and medical sectors, to name but three, component supply gets ‘difficult’ long before the customers products themselves reach their ‘end of life’. Component manufacturers work to a commercial agenda; when the popularity of a specific device wanes, or indeed when new features are demanded by the market, they will cease production and redeploy their manufacturing capacity to devices that are being demanded by their high volume customers; the global players.

When we were children,our parents always warn us "Do comparison shopping before you buy",why they say like this?this is a very simple truth, for the first deal,we are always cautious, through continuous comparison in order to find out the best quality, service, after-sale and price. This apply to any industry,there are many manufacturers of environmental test equipment. When some customers inquire a temeprature humidity test chamber, they will find a very common problem. Why is the price of the same equipment quoted by the two manufacturers very different? 1, the chamber body process,which effects the exterior case quality,this price has a gap. 2, the components, esp.components of the refrigeration system, is the core value of the temperature humidity test chamber. 3, even if the body and refrigeration components are the same, some prices are different, that is the manufacturer technical level. 4, regional issues, Wuxi,Changzhou, Dongguan, these brands need to know more. 5. after-sales, a powerful manufacturer often with a sound after-sales service dept.. The above are both technical and service, as well as the delivery cost of goods to the local and overseas are different.

Times are tough! Sales are down around the globe and it's getting more and more difficult to make a buck in the electronics industry. We all now have our cell phones and our big HD TV Screen at home so little of our materialistic world is unsatisfied. So how do we keep the doors open in 2009, let alone assure our future in the 21st Century?

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...

Here Chris talks about the pitfalls, the paucity of safe options for manufacturers seeking rare components, and his exasperation with organisations that appear to shelve common sense at the first sign of a shortage. He shares his ‘no nonsense’ approach to getting things right first time, and explains his thinking in establishing an independent distributor focused exclusively on delivering 100% component integrity.

In the quest for quality, selecting the right Statistical Process Control (SPC) Software system doesn't boil down to a simple functional "fit-to-requirements" anymore. Once the expert domain of highly focused, independent software developers, the competitive landscape has changed dramatically with the influx of big-name ERP software providers who are aggressively promoting integrated quality modules within an all-encompassing business application framework.

The perennial question in electronics design and manufacture is: "How do I design a printed circuit board (PCB) so that it can be properly tested?" To achieve this objective, there are a number of design-for-test (DFT) considerations and techniques. Some are major, others, minor. However, the total contributes to a highly effective PCB design so that testing procedures applied to a given design result in high 90 percent plus test coverage.

As demands accelerate for increasing density, higher bandwidths, and lower power, many IC design teams are looking up – to 3D ICs with through-silicon vias (TSVs). 3D ICs promise “more than Moore” integration by packing a great deal of functionality int

The head-in-pillow defect has become a relatively common failure mode in the industry since the implementation of Pb-free technologies, generating much concern. A head-in-pillow defect is the incomplete wetting of the entire solder joint of a Ball-Grid Array (BGA), Chip-Scale Package (CSP), or even a Package-On-Package (PoP) and is characterized as a process anomaly, where the solder paste and BGA ball both reflow but do not coalesce. When looking at a cross-section, it actually looks like a head has pressed into a soft pillow. There are two main sources of head-in-pillow defects: poor wetting and PWB or package warpage. Poor wetting can result from a variety of sources, such as solder ball oxidation, an inappropriate thermal reflow profile or poor fluxing action. This paper addresses the three sources or contributing issues (supply, process & material) of the head-in-pillow defects. It will thoroughly review these three issues and how they relate to result in head-in pillow defects. In addition, a head-in-pillow elimination plan will be presented with real life examples will be to illustrate these head-in-pillow solutions.
