Technology has dominated today’s society. The invention of gadgets and gizmos is no longer isolated to their primary functions, but has also expanded to cover lifestyle and entertainment. What would the world be without these inventions or specifically without somebody creating their parts? We probably wouldn’t have the convenience we have now thus, let’s focus on the key component of our beloved electronic devices, the printed circuit board.
What are Printed Circuit Boards?
Printed Circuit Boards or more commonly known as PCB is the part of an electronic device, which manages the traffic and distribution of signals and power throughout. Composed of a copper sheet, these boards have engravings that serve as path for signal transmission. PCB’s are present in almost all gadgets like phones, tablets, laptops and TV. Without it, we would still be back in the Stone Age.
How are PCB’s made?
Printed Circuit Boards are made of alternating material made of fiberglass, conductor sheets, metals, nodes and bits that are layered to create a single piece. Layering depends on the needs of a particular device. Some need two while others need four or more. Manufactures like us at pcbnet.com provide these options to customers prior to fabrication, with low discount rates for first timers.
How to Determine Quality PCB Boards?
Not all circuit boards are created equal. All of them may look alike, but the difference lies in the materials used in creating one. Most customers are clueless when purchasing these parts and can easily get duped into getting the cheaper but inferior sets. Skilled and longtime makers like us at pcbnet.com provide transparency to our customers so we can give them premium items.
For those who still lack ideas on what to consider when planning to get PCB’s, here are the materials to check out:
Fiber Glass is the usual base for printed circuit boards. It provides sturdiness to the item. FR 4 is the most popular version of this and clients must be aware of its thickness. If a customer specifies a malleable type of PCB, materials like Kapton or similar heat-enduring plastics may be used.
Cheaper alternatives such as Epoxies or Phenolics may also be used as board material but they are floppier compared to the previous. They also have a certain burnt smell when soldered as these materials melt easily under high temperature.
Thin Copper sheets are fused on the sides of the base using adhesives or heat-melted metal. Low quality versions only have one sheet on a side but we choose the standard double-sided version. The copper is the conductor which creates a pathway of the electricity for the entire system.
Copper sheets can be layered to a specific amount, provided it does not become a weight burden. Copper sheet weight is measured in ounce per square foot and the standard size used would be 1 ounce per square foot. However, high powered devices may use 2 or 3 ounces.
• Solder mask
The colored material above the copper sheet is called a solder mask. It often comes in green hue but some companies prefer other colors as their trademark. Solder masks are used as barrier between the other materials that may leak or become grounded. It also keeps most of the bits in their place.
• Silk screen
Labeling is easier when the printed circuit board has a silk screen. Manufacturers added this feature so that technicians can assemble the parts more conveniently. Any color is possible, but most prefer to use white for greater visibility. You can place silk screens on any side of the piece or on both sides.
The above mentioned are only the basic things we need to cover. Other parts are also valuable but details are not necessary. Most manufacturers will discuss these aspects while online shops often have them on the description page of their websites. Skilled fabricators like us at pcbnet.com have a dedicated order form with specifications that you can choose from so it’s easier for customers to give their instructions. We have been in the business since 1985 and we completely understand client needs.
When choosing printed circuit boards, it’s difficult to pick the best when the buyer has little information about the product. The better alternative is to find reliable suppliers who guarantee customer satisfaction upfront. Try reading website reviews to check which manufacturer received approval from most clients. If you have time, visit us at pcbnet.com so our very first company customer, who’s still with us until now, can tell you all about his experience.
