Flexible PCB Fabrication

A flex PCB or flex circuit is a patterned arrangement of printed components and circuitry that makes use of flexible based materials with or without a flexible coverlay. The components used for rigid PCBs can also be used for electronic assembly and flexible PCB fabrication.

A flexible PCB can be used in a variety of applications.

PCB FabricationMost of the time, they are used along with complex and advanced components. In fact, flexible PCBs are widely used in daily electronics and technology. They are prominently used in desktop printers, portable electronics and devices, and hard disk drivers. They are also extensively used in other industries and applications such as communications, transportation, consumer electronics, military, automotive, aerospace, medical, and industrial.

In transportation, flexible PCBs are favored because of their resistance against movement and vibrations. Their light weight and flexibility allows them to absorb vibration and reduce its impact to the solder joints in its connections. Flex PCBs can also be used with materials designed to operate in harsh environments. They can be built with waterproof, shock proof, moisture proof, and corrosion resistant materials.

The advantages of flexible Pcb fabrication are countless. Servers and mobile phones, regardless of use and size, are designed to be efficient, flexible, and lightweight using flex PCBs. The most prominent advantage of flex PCBs is flexibility. Their elastic nature allows placement around folds and edges. They also require very little or no wiring, making them less prone to failure and more reliable.

In addition, flex PCBs allow for weight and space savings for up to sixty percent. They can even reach as many as two hundred thousand bending cycles since they no longer require the use of connectors in 3D designs. They have thin inner layers as well as heavy copper layers. The thin copper layers are flexible while the heavy copper layers are ideal for high power usage.

Nevertheless, you should also be aware of the disadvantage of flex PCBs. For instance, flex PCBs are more expensive than rigid flex PCBs. They have low temperature threshold and can be quite difficult to assemble. They can also be damaged easily if not handled with care. They are actually prone to denting and bending. They are also prone to scratching. Once damaged, flex PCBs can no longer be repaired. Hence, it is crucial that they are stored in sulfur free plastic in order for them to stay in good shape.

If you are in search of a complex multilayer flexible PCB or double-sided flex circuit, you should choose a manufacturer that can provide you with the necessary expertise, capabilities, and guidance so you can turn your concept into reality. There are a lot of manufacturers involved in PCB fabrication that can provide you with heavy copper flex circuits which you can also couple with flexible thin copper layers for handing heavy power currents. Go for a manufacturer that builds heavy copper boards that have flex portions, so you can control any voltage additions.

In electronic applications, multilayer flex boards are used for better speed performance. However, using these boards also cause flexibility loss. Hence, it may be more ideal to use double-sided or single-sided multilayer flex PCBs. These boards may be used for complex and unique layouts. They are actually much better than FR4 boards since they have a higher combination possibility.

Multilayer flex PCBs are similar to multilayer FR4 boards in the way that they can both be designed using buried and blind vias. Both of them can also use PTH or plated through holes. You should choose a manufacturer that pushes the limits on their PCB fabrication technology. For instance, you should go for a manufacturer that uses very fine one mil traces.

Lanyards for the Prevention of Hazards

A lanyard is arope-like material worn around a person’s neck which has loop of wire or thread or even an adjustable hook as an end, enabling the object to grab unto things. This is primarily used to hold things such as gadgets, keys, even different kinds of cards, in order for a person to easily bring these things as one and to also prevent himself or herself from forgetting to bring the said things.

From an unobserving point-of-view, a lanyard seems pretty useless because there are other ways a person can bring things, like the use of simple bags. But, given a hazardous situation in which unfortunate events happen, lanyards could be really proven useful. Imagine a scenario where a sudden blackout happens and the person couldn’t see anything, leaving him or her unable to rummage his or her bag for a source of light, what would he do? If the person was fortunate enough to have a lanyard with him or her with a penlight attached to it, or even his or her own phone, then things would turn up for the good.

LanyardsAnother scenario likely to happen is an attempted assault, like plans of stealing or even kidnapping. What if a person suddenly stumbles upon a deranged person in the middle of the night without any people around, what chances will he or she would be able to protect himself or herself? Finding time to look for a weapon at the surroundings will be very hard, even with the possession of it inside a carried bag if there is, and running is a risky option. But then, if that person has a lanyard with a self-defense weapon attached to it, then he or she could really have a chance.

In modern times, unfortunate events are likely to occur, and they are inevitable. The best way to act is be prepared always, and by being prepared, one has to be alert and should be able to have all of his or her needed things close to him or her at all times. And clearly one method of doing this is through the use of lanyards. By attaching important things such as an identification card, self-defense weapons such as a small knife or even keys, one could be able to spare his life. He or she would be able to protect himself or herself by using these tools, and if the unpromising thing happens, at least someone would be able to identify that person.

Aside from the prevention of hazardous events, lanyards could also serve as a person’s way of recognition, be it from a company or from a school he or she is currently at.

These could also be a form of handling the security of a place by having all the members of a community or organization lanyards with the same logos and/or designs, these could also be a way of showing unity and cooperation of a certain group. With all of the mentioned purposes, a lanyard is, without a doubt, a very useful thing to have on a person. Be it for bringing certain tools or personal stuff, or for representation of being a member of a group.

In conclusion, no one should underestimate the usefulness of a lanyard, even if it just looks like a plain accessory. Aside from enabling a person to bring needed things with him or her at all times, it should also enable him or her to have easy access on these things because they are technically just clipped on by just above his or her chest. Enabling a person to have easy access to these certain things also enable him or her the chance of protecting his or her life in hazardous situations, just proving how much of a help a lanyard truly is.

Engaging and Inspiring People: Secrets of Motivational Speakers

Various organizations and companies get motivational speakers in order to inspire and motivate their members. These speakers are usually invited during big gatherings, when majority of the members are present. The ultimate goal is to inspire people to make a change in their attitude, mindset and behavior. When they are spurred into action because of a nugget of wisdom taken from a speaker, then the speech is considered to be successful.

What are some of the ways that motivational speakers engage and inspire people? Is there a secret formula that successful speakers follow?

Successful speakers usually have fresh ideas to share. These unique ideas are usually something unheard of and will add to people’s knowledge. These new ideas will also be able to help the audience become better in the many facets of their lives.

The speaker should be aware that the speech should be focused on altering attitudes, instigating new approaches, and getting a commitment to accomplish a common vision. The speaker should be able to stick to these main goals.

Even without fresh ideas, speakers can still be successful if they are able to share old insights or knowledge from a brand new perspective. They are able to inspire the audience to look at old ideas in a new and different light. This means that speakers should always be up to date when it comes to current trends and innovative ideas.

Another way of engaging the audience is to have a message that is relevant and timely. Messages will be well-received if they’re useful and applicable to the audience’s current situation. The very best speakers often focus on a few simple themes and a central idea, mainly to make the message clearer.

Motivational SpeakersGood speakers are aware of their audience and are able to adjust their speech and message accordingly. This requires flexibility on the speaker’s part. They are not self-centered, but audience-centered, always considering the audience’s perspective. They are sensitive enough to “read” the audience and see if they are responding positively or getting bored.

Motivational speakers inspire people not just at a psychological level, but also on an emotional level. Inspiring people profoundly is a challenging task, but great speakers are able to do it through a variety of techniques. One way of inspiring audiences is helping people focus on opportunities instead of problems. The speaker will not cover up or deny the existence of challenges, but is optimistic enough to be able to see the positive side of tough situations. Listeners are made to realize that things are not as bad as they seem.

Relating personal experiences of failures and triumphs is one way of connecting and inspiring audiences. Almost all speakers use this technique because it is very effective. Good motivational speakers always reflect on their own lives, and pick out stories that may be helpful to others. The ability to tell one’s own life story is a skill that could be honed with practice. A compelling story draws in the audience, and excites and energizes them.

Sharing your own life story also requires a certain degree of fearlessness. Successful speakers engage and inspire other people by opening up about their lives. This type of authenticity is felt profoundly by the audience because it connects to their humanity.

An inspiring speech also needs something to break the audience out of an expected rhythm and jolt them through a surprise and dynamic twist. This requires preparation and a lot of thought. When done effectively, the audience will most likely remember the message and will hopefully be inspired into action.

By now, you should realize that the secrets of the finest motivational speakers are not that complex. They may be challenging to apply, but they are not impossible to adopt.
