Abbreviated as PCB, the printed circuit board is a thin plate which holds electronic components. PCBs can be found in most, if not all, electronic devices. It is a key component of electronics.
Through the years, developments in both the materials and production methods used have contributed to the advancement of the design of printed circuit boards. This article will discuss how PCBs are made.
Printed circuit boards are composed of layers of different materials fused and laminated together using adhesives and heat. The substrate part of the PCB gives the board its thickness and rigidity. This layer is usually made of fiberglass, but other materials like epoxy can be used as well. The copper foil gives the board conductive surfaces and is where components are soldered or stamped. Depending on the design and purpose of the board, the copper can be on one side, both sides, or in multiple layers of the board. The copper areas are laminated with a thin layer of lead to prevent oxidation.
Making the substrate
The roll of woven fiber glass is unwound and then fed to the process station where it is coated with epoxy resin, either by spraying or dipping. The coated fiberglass is then passed through rollers until the desired thickness is achieved. This process also removes the excess resin.
The substrate is then semicured by passing it through an oven. The substrate is cut into panels after the curing.
The large panels are then stacked in layers, with the copper foil in between and then pressed together while being subjected to high temperature. This process fuses the copper foil to the substrate’s surface and also cures the resin fully.
Plating and drilling the holes
A few panels of the substrate are stacked, one on top of the other, and are held together to keep them from moving. Holes are then drilled according to the design or pattern desired. The holes are cleaned to remove extra material clinging from the edges.
The inner surfaces of the holes that are meant to conduct are coated with copper. The other holes are plugged to prevent them from being coated.
Etching the circuit pattern on the board
The printed patterns on printed circuit boards are created using either an additive or a subtractive process. Copper is added or plated onto the substrate’s surface according to the predetermined pattern. If using the additive process, the rest of the surface is left unplated. When using the subtractive process, the whole surface of the substrate is plated with the copper foil then the areas that are not part of the desired pattern are removed through etching. Tin-lead is added to the surface of the copper foil to protect it from oxidation.
Adding the contact fingers
Contact fingers are added to the substrate’s edge so that they connect with the circuit print. The area is masked and then plated. The plating materials applied (in order) are tin-lead, nickel, and gold.
Sealing and cutting the panels
The panels are sealed with epoxy which protects the circuit patterns from getting damaged while the electronic components are being attached. This is also the part where instructions, symbols, and other marking are added through silkscreen stencil.
When the stenciling process is finished, individual printed circuit boards are then cut from the panels. The edges of the boards are then smoothed.
If the PCBs will not be used immediately in production, they are packaged individually into protective plastic wraps (often the antistatic kind) and then stored or shipped.
Those are the basic steps in the manufacture of printed circuit boards.
Printed circuit boards with Pcbnet are composed of layers of different materials fused and laminated together using adhesives and heat.
Life hacks are simple, practical tips to go about everyday mundane tasks that make use of available resources. Not surprisingly, there are also life hacks that utilize psychological concepts that usually fly over people’s heads. Motivational speakers are all about delivering life-changing pieces of advice and nuggets of wisdom to a mass of people. If they want to succeed in doing so, they must first master the art of conversation and oration.
There is a list of psychological life hacks that is being circulated throughout the Internet, and motivational speakers can use some of those life hacks in the list to further enhance their conversation and oration skills.
“Pay attention to people’s feet.” The motions of the feet determine if a person is actually interested in continuing a conversation or even initiating a new one. If the feet do not move even an inch, that means the person(s) is/are either not interested in the conversation that is being initiated by the speaker or wants an ongoing conversation to end. For the motivational speaker, he/she should always watch out for the motions and directions of the feet of the audience. If their feet do not face towards the direction of the speaker, this can mean either one of two things: the motivational speeches the speaker gives are boring, or the audience is simply not interested in what the speaker says. The motions and directions of the feet are part of what is called body language.
The foot-in-the-door phenomenon suggests that people are more likely to agree to do a task if they are asked to do something simpler first. Motivational speakers in general should not impose the heaviest of tasks on people too early. They should take it slowly and surely to earn the audience’s trust. Commitment can be achieved with flying colors if it is being done gradually. If the audience says no to an impossible task, the speakers should devise something less difficult on the fly.
Cognitive dissonance happens when a person encounters two conflicting sets of beliefs, ideas, or values. A motivational speaker must know this very well in order to reach his or her targeted message, especially if that message conflicts with the mindsets of some members of the audience. Cognitive dissonance can be used in a positive way by having the speaker ask the audience for a small favor. Once the dissonance disappears, the audience will gradually believe in what the speaker says.
Stage fright is one of the most common fears people can experience. Even the most veteran of motivational speakers can still experience this type of fright. One way to deal with stage fright is to chew a piece of gum moments before the delivery of the motivational speech. This is because one of the symptoms of stage fright is a dry mouth. Chewing gum helps avert the drying of the mouth and helps calm the mind before the big oration by soothing the nerves that reside beneath the teeth.
Another manifestation of body language that suggests the audience’s interest in the speeches the speaker delivers is how the members of the audience gaze. If they tilt their heads towards any direction other than the speaker’s, that means they are not interested in the speeches. The speakers themselves should also maintain proper gazes and should tilt their heads towards the directions of certain members of the audience only when necessary.
People will not remember what is being said, but they will remember what they have felt. To achieve this effect, the speaker must bring out everything in his/her speeches to not just drive the point across, but to strike them at their hearts. Be eloquent, but also be mindful of what the audience will feel.

Prohormones are compounds that enable the body to produce anabolic steroids. These are legal substances because the conversion of steroids normally takes place in your body, and the body limits the amount it can produce. The conversion occurs in the liver and the enzymes found in the body should be present in order for the process to happen. The prohormones enhance the existing hormones, as compared to steroids that add hormones in the body. It is basically a variety of testosterone.
It is important for prohormones to complete the cycle correctly and limit the amount of time it takes. Luckily, even in small amount it can provide the results that you want in muscle gain. Workouts and training are needed for the prohormones to be transformed correctly. Unluckily without the workout there is a possibility the prohormones will be converted into estrogen, which will have an opposite effect. There are some prohormones with added compounds like estrogen blockers as well as built-in liver support. Reducing caloric intake and clean diet are suggested for better results on prohormones.
Athletes and body builders buy prohormones to increase muscle mass, and increase the strength and size as fast as possible. It also can help in faster recovery time from workouts and maintaining endurance if needed. The substance can definitely provide results and are safe for women in small amount. Those with wasting diseases can achieve great results after taking prohormones. It also helps them maintain their normal body weight. Older men buy prohormones for hormone replacement therapy purpose.
There are some side effects involved in taking prohormones. The effects will depend on the user and the type of prohormone. Some of the common side effects are prostate swelling, acne, or hair loss, but are minimal. It is important for some individuals to be careful. The prohormone cycle would last around 30 days. For others it is suggested that a liver support supplement is taken to make sure they will achieve the best results of conversion. The average shelf life of the substance is 2 to 3 years.
Once the prohormone cycle is completed, it will leave the body right away. Essentially, your body will lose strength and size and gain fat post cycle. This is the reason why a Post Cycle Therapy is recommended. In order for the body to get back to pre-cycle quality, a PCT will help to recover testosterone, promote strength, estrogen inhibition, minimize fat gain and cortisol and restore.
After a prohormone cycle is completed, the compound immediately begins to leave the body. Essentially your body is ready to lose size and strength and gain fat post cycle. This is why a Post Cycle Therapy is highly recommended.
A PCT is needed to get your body back to the pre-cycle quality. This will help with testosterone recovery, promoting strength,cortisol, estrogen inhibition, minimizing fat gain and restoring overall health. Before starting with another prohormone, you should complete the full post cycle therapy.

Not all have the liver enzyme needed. Prohormones are broken down into classes. Non-methylated and with less side effects belongs to Class 1. Class 2 is methylated and requires a liver support supplement. The prohormones that belongs to Class 3 and Class 4 are those that have completed the cycles and are accustomed to them already, to avoid harmful side effects.
