– Aprenda como trabalhar com os iBeacons de forma individual (como se fosse setores separados de uma empresa, shopping, hospital etc), e também como trabalhar com eles de forma conjunta (Região), ou seja, todos atuando como se fosse um único ambiente, como se uma pessoa entrou ou saiu da empresa como um todo, e enão de um setor da mesma.
– Na maioria dos exemplos foi ensinado como criar APPs usando o componente tBeacon, que facilita muita a sua vida, mas também como fazer para criar o APP totalmente no btraço (na unha), sem o uso do componente
– Aprenda como fazer para que o local onde possui um iBeacon não apenas saiba que um aparelho entrou no seu raio de atuação, mas também como identificar qual é o celular (código único do celular)
– Além de capturar o código único do celular, também foi mostrado como fazer para fazer uma busca no banco de dados PostgreSQL (usando o servidor de aplicação DataSnap) desse código, caso existe um código no banco, é retorna do qual é o usuario que entrou ou saiu do local, mas se o código não existir, foi ensinado como fazer par que o usuário entre com o seu nome, e então é gravado no banco de dados tanto o código do celular como o nome da pessoa (dono do celular). Desta forma, da próxima vez que o usuário entrar ou sair de algum local, a empresa saberá o nome do usuário, podendo gerar relatórios e estatísticas incríveis.
– Foi mostrado passo a passo a criar os APPs e também como fazer o deploy para os celulares Android e Iphone, para que os alunos pudessem de fato ver que os que foi ensinado funciona nos dispositivos.

Internet of Things PCB ways to care for Startups

Given that IoT devices are so fresh, you would assume that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and facing a great deal of technical troubles and delays. That is most certainly not true.

Nonetheless it doesn’t signify IoT startups have a straightforward way to fame and fortune. Facing them is many different design and manufacturing points that are special to these small products. These points are required to be thought of for the fresh new IoT product to be a success.

On the plus side, it’s very important for IoT startups to find out that the foundation for a successful awesome product exists. This implies experience and knowledge regarding the design, fabrication and assembly of these kinds of cutting-edge products are out there. Additionally, the best advice is for clever IoT product business men and innovators to heed the recommendation that professional electronics manufacturing services or EMS companies have to offer. These businesses as well as their engineering employees have already undertaken the job with revolutionary IoT firms in Silicon Valley participating in the initial phases of this appearing market.

The PCB of an IoT unit is another beast than the traditional one, which is much larger and flat. IoT gadgets, conversely, are comprised mostly of either rigid-flex or flex circuit assemblies, which include their own sets of design layout, fabrication and assembly points and nuances.

Layout

A top thing to consider is to search for experienced designers who’ve finished a great deal of rigid-flex PCB designs. PCB space for an IoT unit is scarce. So you’d like the designer to have direct layout practical experience to proficiently design important parts on that little area.

On top of that, nearly all IoT systems aren’t fixed; they bring appreciable movement and folding. Right here, the experienced designer plays a major role in computing bend ratios and lifecycle iterations as a important part of a design. Some other important design layout points include things like signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are utilized on flex circuits to assure parts installed on the flex circuit remain tightly in position to stay away from movement.

The next factor is through-hole component positioning in rigid-flex circuits. How come is that essential? Most of the IoT devices are founded upon surface mount device(SMD) placement. Nevertheless , there may be through-hole parts, which are commonly positioned on either the rigid section or the flex part of the board. Through-hole parts are normally utilized to communicate input/output or I/O signals to the exterior world. That way, those signals can be displayed utilising an LCD or LED monitor. Through-hole component placement is an important account in an IoT item given that when applied to the flex part of the board, proper stiffeners ought to be designed and applied for ideal assembly.

At last in the layout category, the high temperature which parts bring in should be deemed. IoT systems are becoming more sophisticated with rigid-flex and flex circuits featuring approximately 12 – 14 layers. Several systems are digital. Nevertheless , increasingly analog products are being exercised in IoT products. Analog circuitry generates far more heat than digital ones. As a consequence heat expansion and then contraction rate must be taken into account. In tech lingo, that is called the Coefficient of Thermal Expansion or CTE and the effective treatments for it.

Manufacturing

Selecting the most appropriate fabricator is important and is linked to the EMS enterprise you’ve decided on. The fabricator you want has to have IoT PCB fabrication practical experience. Among important points here are insuring durable adhesions between layers on both rigid and flex circuit sides, comprehending all of the vital calculations and obtaining an excellent expertise in when current transfers from the rigid side to the flex side.

These fabricators also need to have an in-depth expertise in remarkably small parts similar to 0201 as well as 00105 device packages, package-on-package, and the employment of fine-pitch ball-grid array or BGA packaged devices.

Furthermore, they ought to have experience of designing boards with very tight tolerances in terms of footprint for those types of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They ought to have laser drills for via drilling with sizes of 5 mils or under mainly because these IoT units could be so modest that a common drill size of 5 to 8 mils may well not be all you need. They might have to go to a 3 mil, meaning you have to have an advanced laser drilling capability in house.

In the event that you’re placing via-in-pad, it’s a great way to make use of the small space that’s available on the rigid-flex board, nevertheless , it creates problems for assembly. If vias are not 100 % planar or flat in shape, it will be a difficulty over the assembly of those tiny BGA packaged devices. This is because non-planar surfaces can put in danger the integrity of solder joints.

In some cases via in pads leave bumps when they’re not scoured correctly after laying the vias and gold finish at the top. When there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices wouldn’t be an ideal joint. This might create occasional connections, which might be a bigger issue to cope with and repair. It all boils down to which EMS enterprise you’re working with because they’re the ones who will pick the fabrication house to make a successful IoT product for you.

PCB Assembly

It’s essential to go to experienced EMS companies that have successfully assembled IoT and wearable PCBs since they have specialized tooling and fixtures already out there, which are vital for assembly in order to guarantee components are placed effectively, precisely and the printing is carried out in the correct way.

Printing could be a obstacle for IoT products. If it’s a rigid-flex board, then you can find a change between thicknesses of the rigid and flex circuit portions, meaning a special fixture is necessary to retain the complete rigid-flex board planar or absolutely flat to get effective printing to be realized.

Startups must be set to decide on the proper manufacturing partners and EMS firms. In this manner they can confirm they’ve adequate experience beforehand to get the multitude of design, fabrication and assembly details efficiently performed as they are key to a triumphant and timely IoT product launch.
