PCB NET SPECIALS – 9 IMPORTANT THINGS TO KNOW ABOUT PCB

Printed Circuit Boards or simply known as PCBs are basically present in every electronic device nowadays. PCB interconnects different electronic parts of a device for it to operate successfully. In early 1900s, PCB is hard to manufacture but with the advancement of technology over the years, it became commercially available for different businesses.

To celebrate how PCBs revolutionized the electronic industry throughout the years, here are some important PCB facts:

  1. PCBs are first mass-produced during World War 2

PCB, Before World War 2, PCBs are hard to manufacture. Each printed circuit board is made manually and soldered individually. When the PCB technology was used by the US Army for proximity fuses in the battlefield, automated production of printed circuit boards was developed. After the World War 2 ended, automated manufacturing process of PCBs was released commercially and used by different businesses in the industry.

  1. Most PCBs are green due to the glass epoxy used

Years ago, PCB manufacturing companies, like us here at PCBnet commonly use glass epoxy in the board. Glass epoxy is naturally green in color so early versions of printed circuit boards are all green in color. Nowadays, the finishing color of printed circuit boards can be any color as most companies use solder masks for the board’s base.

  1. PCB companies use CT scans for quality checking of PCBs

Ct scans are not only used for medical purposes as PCB companies use them for quality control of PCBs produced. Through the CT scan, 2D and 3D images of the printed circuit board are produced to check proper placement of circuits and soldered connections. This new technology in quality control of PCBs is best for complex printed circuit boards of big machines.

  1. Resistors, capacitors and diodes are the most critical parts of PCB

Most PCBs have three most important parts – the resistors, capacitors and diodes. The resistors protect the device from excessive energy flows. It works like a fuse. On the other hand, capacitors are the warehouse of energy within the circuit. It stores electrical signals and works like a battery. Lastly, diodes are the ones responsible for ensuring one-way energy transmission. It ensures that the energy flows in one direction only inside the circuit board.

  1. Static electricity damages the most sensitive part of PCBs

At PCBnet, we advise clients to avoid any source of static electricity when handling printed circuit boards. Static charges may damage the most delicate parts of a PCB. Once damaged, it is difficult to repair defective parts especially the embedded copper layer etches of the board. To prevent this, it is best to use anti-static bags when handling or transporting printed circuit boards.

  1. Most PCB companies follow class 1 and 2 standards for manufacturing

pcbPCB manufacturing has three quality standards – class 1, 2 and 3. Class 1 is for general electronic devices. Testing and verification of designs also fall under this class. Class 2, on the other hand, is for special service electronic devices that must be highly durable. Examples include telecommunication devices and business machines. Lastly, class 3 is for specialized electronic devices. Electronic devices in the medical, aeronautic and military fields fall under this class. We, at PCBnet, as a mass-producing company, follow class 1 and 2 quality standards when it comes to manufacturing.

  1. Printed Wiring Board (PWB) and Printed Circuit Assembly (PCA) are different from PCB

Printed Wiring Board or simply known as PWB is a plain board lined with copper tracks. It does not contain other circuit elements like resistors and capacitors. On the other hand, Printed Circuit Assembly or PCA is a PCB populated with many electronic components. It is capable of doing a lot of electronic functions for the assembled device.

  1. It is difficult to repair PCBs

Copper sheets are laminated against the board to preserve delicate electronic etchings and connectors. However, printed circuit boards for heavy-duty use are sometimes added with conformal coatings to preserve soldered components. These types of PCBs can withstand extreme conditions, like high temperatures and corrosion. However, because of the conformal coating, repair of PCBs is difficult so replacement is usually recommended.

  1. It is possible to order PCBs online

At PCBnet, we offer to give quotes to interested clients online. Placing the final order is tricky at first, but we can assist clients in specifying the details of their PCB order. Years before, it takes several days up to weeks before PCB manufacturing companies can give quotes to a planned order. Fortunately nowadays, online inquiry of PCBs is easier by using web-filled forms.

WHAT MAKES RUBBER WRISTBANDS VERY CATCHY AMONG KIDS?

Rubber wristbands are some of the most popular accessories for both kids and adults. They come in different colors, designs and sizes. These bracelets are also used as giveaways during social functions, gifts to friends, or fund raising items. Today, they take another form which became more popular among kids ages 7 to 14. These wristbands are called loom bands.

What are loom bands?

Loom bands are rubber wristbands created by using small colorful plastic rubber bands and a plastic loom called the rainbow loom. These are sold or swapped by kids after creating it themselves.

The rainbow loom is a plastic loom invented by Cheong Choon Ng, a Malaysian immigrant of Chinese descent. He came to the US in the year 1991 where he graduated with a degree in mechanical engineering at Wichita State University.

In 2010, he came up with the idea of creating a toy which looms rubber bands into colorful bracelets. He had the idea while watching his daughter create colorful rubber band accessories.Rubber Bracelets

Ng’s prototype used wooden board, pushpins and dental hooks. In 2011, he had the parts manufactured in China which he and his wife assembled later in their home. He later renamed it Rainbow Loom, a name his brother and niece suggested.

Rainbow Loom Revolution

Rainbow Loom’s sales didn’t kick off until Ng started creating instructional videos. The videos featured his daughters creating different loom bands. In 2012, he received orders from Learning Express Toys, a specialty craft store. After that, the Rainbow Loom’s sales kicked up. Soon, Michaels, a craft retail store, started selling these too which signaled other retailers to start having it in their own stores.

In 2013, the Rainbow Loom sold around 1.2 million units.

Loom Band’s Popularity and Kids

Kids love colorful and shiny outfits. Items that display these instantly became a fad. At present, loom bands hold the record when it comes to practicing a child’s focus. It also gave them an item they can share with friends.

Rainbow Loom targets a market of 7 to 14 year old kids. As they weave colorful and shiny rubber wristbands, their creativity gets practiced. Some kids even started their own instructional videos in creating their own loom band design.

To create these colorful bands, kids use the following materials.

1. Rubber bands
2. Plastic Looms
3. Hooks
4. C-clips

The above mentioned materials are also available when you buy a Rainbow Loom set. If you wish to learn how to make one, there are plenty of instructional videos available in the internet. You can also catch Ng’s own instructional videos for Rainbow Loom users. His videos had already hit 4 million views.

Loom Bands for Every Occasion and Use

Since it was first released, loom bands became a very popular pastime for kids. Summer camps and clubs use these to help develop kids’ creativity. Grade school kids treat these rubber wristbands like friendship bracelets and swap these with friends.Charity Wristbands

Loom bands are also used to promote a cause. Last 2013, third graders from St. John the Worker school in Pennsylvania, had a “Rainbow Loom-A-Thon” where they created loom bands for cancer patients. The fad also inspired Suzanne Peterson to create a 204 page book entitled “The Loomatic’s Interactive Guide to Rainbow Loom”.

The Fun in Loom Bands

Loom bands are perhaps today’s most popular type of rubber wristbands. It is simple to create, colorful, and helpful as it harnesses a child’s creativity. For parents who are thinking of a great toy for their kids, this is perfect for them. It also keeps them focused and busy. This is one hobby you can enjoy with them.

the-wristband-factory.com offer rubber wristbands that are also available in a range of bright colors, which makes the wristbands an effective way to promote or publicize a good cause, a business or a sports team.
