Detroit Michigan Solder Training

Detroit is one of the most influential cities when it comes to the overall economy of the United States. It is recognized as the capital of the world’s automobile industry, but other important sectors also contribute towards its economy. These include finance, life sciences, information technology, advanced manufacturing, as well as engineering.

With America’s three biggest automobile companies situated in the city, manufacturing plays perhaps the biggest part in its economy. Over 500,000 workers are employed in ‘high-tech’ industries, with 70,000 in automobile manufacturing alone. Not only is this industry key for providing jobs in the city, but it also contributes significantly toward tax revenues. A Center for Automotive Research study showed that $91.5 billion and $43 billion were paid to both state and federal tax respectively 2010.

Detroit is certainly developing in other fields as well, and is one of the top five financial centers in the United States. It is also ranked 5th for employment in the emerging technology field in the country.

With the automobile industry at the forefront of the city’s industries, and the a larger emphasis is placed on workers with a particular skill set.

Kentucky Solder Training

Kentucky is a state with great opportunities. Long a home to some of the nation’s agricultural and mining industries, it is also a place where electronics manufacturing and energy production is growing. Much of the electricity in the US is produced with enriched uranium or coal which comes from Kentucky, and the state has natural resources that could be important for a range of emerging industries in the tech sector.

While Kentucky has always been known as a state with great mineral resources, much of the mining has left for countries where resources can be obtained at a lower cost. In the place where mining once was, industries like manufacturing and energy production stepped in to fill the void. However, mining still has a place in the current and future economy of the state, such as the mining of Kentucky’s clay for the building of superconductors.

Due to resources being needed for the production of high-tech items and manufacturing facilities around the state, it only makes sense that advanced manufacturing firms would look to Kentucky as a likely place to do business. Additionally, businesses are attracted to the state because of its dedicated workers and lower operational costs. To bring these investments to the state, workers will need skills like Kentucky solder training.

Businesses that want to compete for many of these advanced manufacturing contracts will need employees that can perform the work that companies need.

Iowa Solder Training and Certification

Iowa is a state with a robust and diverse economy (anon on of the “filtering” states for helping us to choose new presidents). For many people that are not familiar with the state, they assume that farming is the primary economic driver. While farming may be an important part of Iowa’s economy, it is really only one piece of a much larger picture that includes advanced manufacturing, biotechnology and renewable energy.

In recent years, one of the fastest growing sectors in the economy has been the tech industry (with a great degree of emphasis on electronics). With Iowa being a particularly business friendly state, it has attracted millions of dollars in investment from some of the leading names in tech. Iowa attracts interest from information and technology businesses because it offers a low cost environment, strong infrastructure, and a workforce that is well-educated.

To stay competitive, the state government and the business community will need to continue to work and provide this attractive environment. Keeping the cost of business low, and providing great opportunities for investment will help, but an attractive workforce with advanced skills like Iowa solder training, will always be a key factor to keep the state’s economy growing.

Electronics manufacturing is a skill that is in high demand in the modern manufacturing sector. With that being the case, many of the technical firms in the state will need Iowa solder training for their employees. With the soldering instruction team at BEST, employers get professional training opportunities to ensure that their staff has the skills that attract investment.

QFN Stencil

The most widely placed device type in this era of handheld, wireless devices is the bottom termination component or BTC. The most common package families within the BTC realm are QFNs, LGAs and LCCs. The primary drivers which have made this package style so pervasive are its very low cost, its low profile to the board after reflow in order to keep the profile of the electronic device thin, exceptional RF performance and ability to dissipate a lot of heat through its large central thermal heat sink.

For the initial placement of these leadless devices it is imperative to make sure that there is enough paste printed on the board location for this device in order to make sure that there is a good electrical and thermal contact in the center ground area while there not being too much such that the IO pads are shorted between them. There has to be enough height underneath he device to be able to get the cleaning agent underneath the device. Typically when printing paste for these leadless devices a portion of the center ground is “window paned” or reduced in solder paste volume in order not “crown” or lift up the center of the device and have no connections at the IO pads.

Stencil for QFN Rework

Reworking QFNs can be done in a multitude of different ways but the one using a QFN stencil is the simplest and requires the least amount of dexterity and outside tools. In method IPC 7711/21 Procedures 5.8.1.1 and 1.2. In these methods the bottom of the QFNs end up with solder “bumps” in a controlled fashion so that they can placed almost as easily as BGAs. After cleaning the bottom of the device a QFN stencil is adhered to the bottom of the device and adhered over the pad location with a adhesive backed plastic film stencil. Solder paste is then rolled in to the apertures using a micro squeegee until all of the apertures are filled with solder and the excess solder paste is wiped away. After reflow, the stencil is removed and the device is then cleaned. You are now ready for placement using tacky flux and some form of controlled temperature heat source. In the sister procedure another QFN stencil is placed on to the board to guide the “bumps” in to the correct location. In both cases the QFN stencil simplifies the process and simplifies the tools required for rework while speeding it along.

PCB Prototype Stencil

When you have an excellent new idea requiring a new printed circuit board to be assembled and built up it is imperative to have a way to be able to test out the concept quickly. With today’s heavy slanting towards surface mount devices, the assembly of such boards has become easier. If the majority of the components are surface mount parts then the fastest way to build up the printed circuit board is to print the paste using a stencil, place the components on to the printed pad areas and then reflow or heat up the solder to where it melts and flows out to the pads.

In building a prototype PCB there a variety of DIY tools that can be used. For simple prototypes the tool list includes a squeegee (could be credit card or plastic paint scraper), a prototype PCB stencil, blue tape, printed circuit board holders, a toaster oven with simple controls and some type of magnified inspection system. In terms of materials solder paste and ultra pure isopropyl alcohol will be needed. See the complete PCB prototype printing process here.

Metal Foil PCB prototype stencil

If we look closely at the prototype SMT stencil there are few different types of material which can be used t fabricate this stencil. One common material is a high nickle content stainless steel. The high nickel content dissipates the heat readily that is generated by the solder ablation process. In addition these alloys tend to have fine micro grain structures which allow for the solder paste to be released easily and consistently. The other common material is Kapton™ a highly temperature –resistant polymer strain. Again this reduces any “waves” that may form in the material which will not allow for there to be a clean release of the solder paste form the bottom of the stencil. The ability of the material to retain its dimensions also makes it an ideal material for prototype PCB stencils.

In order to see the differences in these stencils please review the technical paper on their performance here.

IPC-A-610 F Standard

The latest IPC standard on the acceptability of electronic assemblies is revision “F” dated August 2014.

IPC-A-610F Standard

This standards book lists via illustrations and photographs the acceptability of rigid, rigid-flex and flex assembled circuits. This document contains the latest industry guidelines and specifications with respect to soldering, soldering fillet geometries, PCB hardware, wires, boards, components as well as terminals. This is a tool in which  OEMs can speak with their contract manufacturers regarding what is “acceptable”, what is a “defect” and what is a “process indicator” on a finished assembly depending on the class of product. Defined in the specification are the different classes of products with Class I products having just having to be able to operate, Class II products being able to operate on a continuous basis and Class III products where the continued operation of the board is critical to an operation.

This standard book has an associated training program which is designed for quality, sales, purchasing, material control and process engineers involved in the manufacturing and procurement of printed circuit boards. In this training program companies can either send an individual to become a trainer in these teaching theses standards (a CIT-certified instructor trainer) or the company can hire a trainer to train their staff in the latest standards. These specification books are used in the classroom as part of the teaching along with instructor-supplied “war stories”, examples, photos and other tools. In order to speak to someone about solder training to see what some of your options are look here. The training can be accomplished via a solder training company who hods the IPC license.

These standards can be purchased on Amazon IPC-A-610F Standard or on the soldertools.net website herIPC-A-610F Standard.

What is better… A Mini Metal Stencil or an Adhesive-Backed Plastic Stencil?

We were wondering what was a better performer for PCB rework……a miniature metal stencil or the newer plastic film stencils with and adhesive backing.

Mini Metal Stencil

It was pretty evident that the mini metal stencil had met its match with the adhesive-backed plastic film stencil. The short comings of the metal stencil are well-known. It takes up a lot of PCB real estate making it difficult to use on today’s difficult boards. When printing the technician has to at the same time apply squeegee pressure, which will cause the stencil to shift off pad, while holding the stencil in the correct position over the pads. Post cleaning, especially with 4 mil or thinner stencils, the stainless has a propensity to be bent. This bending causes there to be a lack of intimate contact with the stencil and board and causes smearing of the solder paste.

The mini metal stencils’ counterpart, the adhesive-backed plastic film stencil, has taken over the majority of rework printing applications as it has overcome ,any of these above problems. The repositionable adhesive backing allows for micro adjustments of the stencil over the pads to be printed while at the same time allowing for intimate contact between the stencil and the PCB. Furthermore this backing allows for multiple passes of the squeegee which  means that the apertures are filled up with solder paste consistently. The flexible nature of this stencil allows for it to be placed in to very tight quarters on the PCB making it ideal for today’s high density of circuit boards. Finally. the ability to put a flap in the stencil allows for it to be a barrier which will prevent solder paste from being seared all over the board.
