Major Trends In The Electronic Manufacturing Services Industry

Sunday, September 18, 2016 10:48:59 AM Asia/Shanghai

Technology is always changing, so what does that mean for technology manufacturers and sellers?

It's easy to overlook just how quickly “common wisdom” about the manufacturing industry can become outdated. The Asian markets became so saturated with manufacturing in the last decade that it's ultimately changing the face of the entire market. Costs-of-living in Asian cities with manufacturing centers are now approaching Western levels, which has -predictably- eliminated most of their cost savings.

Some are scrambling to set up shop in even cheaper countries; others are beginning to reconsider the wisdom of outsourcing halfway around the world. They're doing this even while the industry itself, and its needs, are also changing.

So what are the big trends in manufacturing services at the moment, and what areas are expected to boom in coming years? Let's take a look.

Major Trends Worth Noting In The Electronic Manufacturing Services Industry

 

1. In-Automotive Electronics

Smart Carsare quickly becoming the new rage among auto manufacturers. A few years ago, it was only the high-end luxurybrands including hookups for smart phones and tablets.

Now? We're likely only a few years from seeing those become standardoptions. In fact, they may even come to supplant more expensive audio setups in low-cost cars. After all, from a manufacturing perspective, it's a lot cheaper to include an iPod dock than it is to include a full radio/audio player.

And in the meantime, electronics are expected to comprise forty percent of car component costs in 2015.

Or, at the high-end, we're now seeing brands like Lexus talking about full “Heads Up Displays” integrated onto\into their front windshields, to create a driver's view that, in many ways, looks like the sorts of HUDs we see on military equipment. Research in this sector is undoubtedly going to cause a boom.

 

2. Medical Electronics

Another industry showing plenty of growth, and no reason to predict much else, is the medical field. Rapidly-developing countries are buying up medical equipment about as fast as anyone can produce it. They're also looking into setting up their own shops, especially in India, which already has a thriving (if often unlicensed) biomed field.

Parallel to this, of course, is the never-ending drive by the high-tech nations to keep developing better medical hardware.

Either way, current estimates by Frost's are that the electronics manufacturing sector will be worth nearly $40 billion by the end of the decade. It's a wide-open field with room for practically any quality manufacturer.

 

3. Green Technologies

Being Green isn't just for hippies and disaffected Xers any more. As climate change statistics continue to mount, there's increasing pressure from all areas consumers, businesses, and governments to look into more eco-friendly manufacturing solutions. The various carbon cap or carbon trading plans being implemented are also helping to drive this push.

With major programs being launched to drive research in the field, manufacturing concerns who electronic manufacturing can get their ISO certifications in place could see a lot of interest, even in countries that aren't at the low end of the global manufacturing cost scale.

 

4. American Reshoring

Remember when we said Asian outsourcing wasn't much cheaper any more? According to The Boston Consulting Group, manufacturing in America is now only five percent more expensive than Asian manufacturing when all hidden costs are considered.

Considering the major difference in quality assurance and reliability a company gets from domestic manufacturing, that 5% starts looking like a small price to pay to avoid a (literal) world of supply line hassles.

Mexico also continues to grow as a manufacturing base... however, its ongoing political and criminal instability are a serious barrier to investment.

You Can't Relax In Electronics Manufacturing. It's a fast-changing business world, and we all have to keep up if we want to keep in business.

PCB Prototypes Vital to Electronics Market Growth

Friday, September 9, 2016 11:14:49 AM Asia/Shanghai

Imagine a smart phone that thinks like a human brain. Anyone walking along the street or driving on the road often may not realize how their brain is at work all of the time, noticing all sorts of movements at changes along the route. The brain carries out this task at a rapid speed. So is it possible to invent a smart phone that will do the same? PCB prototyping is hoping to one day bring these fantasies to a reality.

 

The Ultimate Smart phone

However good smart phones and computers can be these days, they are not intelligent enough to differentiate between objects in the same way as a human brain does all of the time. The smart phone doesnt know the difference between a human being and a lamp post. But what if it could?

Maybe the phone could tell you that there are some suspicious-looking strangers casing your neighborhood. It could send a message if it notices that some articles in a shop window are on offer at a better price than yesterday.

 

An Ongoing Process

As electronics manufacturers conduct research into these future products, they have to test their ideas all of the time. For those involved in manufacturing printed circuit boards, PCB prototyping is not something to be conducted just once it must happen throughout the entire manufacturing process.

The electronics manufacturer has to ensure that the product works as claimed and is reliable and safe.

 

Customer Communication

As they develop the smart phone that can tell the difference between a person and a lamp post, electronics manufacturers must communicate with customers to see how the technology works in different environments. At some point, the customer will be looking for a phone that not only distinguishes between humans and street furniture, but between humans, animals and trees.

Customers are demanding ever more innovative smart devices that have an increasing array of components in an ever smaller space. The manufacturer has to use PCB prototyping to detect potential problems before they occur, reduce safety risks and keep a firm control on costs.

All this needs investment. Manufacturers have to develop their own bespoke PCB prototyping facilities for each product. They also must invest in a qualified workforce that has the skills to interpret any subtle signs of potential problems during the test stages.

Such testing facilities will also have to be designed to suit customers who buy sophisticated devices that must operate in extreme or critical environments, such as aerospace engines or offshore technology.

SMT Assembly Market Set for Significant Growth

Wednesday, August 31, 2016 10:14:22 AM Asia/Shanghai

Surface mount assembly is a form of surface mount technology (SMT). It is a method of electronic circuit production where components are placed directly on the surface of a printed circuit board. This technology has replaced the earlier method of wiring components to a circuit board through holes in the board.

As a result, the circuit board is smaller than before as it has fewer or no leads. Instead, it connects with other parts of an electronic device through a series of pins, contacts and solder balls.

The equipment used in surface mount assembly consists of robotic machines that are often called pick and place machines. These work at high speed to place resistors, capacitors and other components on the circuit board. The equipment carries out its work according to specific pre-programmed tasks.

The software required to operate these machines has become one of the fastest-growing segments within the surface mount assembly market.

The reason for this market surge lies in attempts over recent years by manufacturing industries to streamline their operations. Rising costs of skilled labor as well as rising energy costs have meant that the manufacturing sector has had to eliminate those operations that were not deemed to have added value, and has had to redefine and optimize other shop-floor processes.

The increasing automation of shop-floor processes has led to a greater demand for surface mount assembly equipment. This has coincided with a drive for efficiency and miniaturisation in the medical, electronic, defense and aerospace industries that has also increase demand for smaller electronic devices and hence surface mount assembly equipment.

The emphasis on product quality has led to a further demand for surface mount technology inspection equipment. This not only reduced repair and reworking costs, but also maintained quality control throughout the production process.

Continuing technological advancement along with burgeoning demand from emerging and developed economies recovering from the 2007-8 financial crisis and recession have contributed to the ongoing growth. The market in Asia has been boosted by a resurgence of demand from China. The health care and automotive industries in particular are likely to boost this market to a global value of US $11.7 billion worldwide by 2017.

The surface mount technology market has become intensely competitive. The problem for new entrants into this market could be financing high upfront research expenditure.

The Impact of Copper Dissolution on PTH Assembly

Friday, August 26, 2016 11:23:06 AM Asia/Shanghai

Plated through-hole - also called thru-hole - assembly, or PTH assembly, provides a method for a connection between printed circuit board (PTH) rack layers.

The principle is to drill or punch holes through the board and then plate, or metallise, them. This is a more expensive method for binding circuit board components than in straightforward surface-mounted technology (SMT), but the binds are mechanically far stronger.

The main advantage of PTH assembly over SMT technology is that, in the latter case, the soldered joints will tend to contract over long periods of time. This is an especially difficult problem in large capacitors and electrical installations such as those used in power generation that may be subject to large mechanical stresses.

PTH assembly faces a number of critical reliability factors. The circuit board material and thickness will determine the power and speed of the drilling machine used to create the holes. If the drilling speed is too great, it could cause rough edges around the holes or a breakdown of the drilling bit.

However, like SMT technology, PTH assembly still has to use solder. Since lead-free tin-copper alloys were introduced into electronic circuitry, copper dissolution has become a major issue in the bonds as well as in the hole plating.

Copper dissolution is a normal phenomenon that occurs on the contact of copper plating with molten tin-rich solder. The copper plating effectively dissolves into the solder. This dissolution is a necessary process for the creation of solder joints.

The dissolution process becomes stronger when there is a greater proportion of tin in the lead-free solder alloy. Copper dissolution is also affected by other variables in the thru-hole assembly process such as the pre-heat temperature of the board and the contact time between the copper plating and the flow rate of the solder fountain. The most susceptible part of the assembly is at the knee of the through hole.

The addition of nickel, silver, antimony, germanium and bismuth to the solder alloy to allow a reduction in the tin content helps to slow the copper dissolution process. However, experts say that while this process may work initially, it will not prevent copper dissolution during any reworking process.

The real solution to this dilemma is a new reworking process for thru-hole assemblies, but this still awaits development.
