Business in the production and sale of printed circuit boards: the device of the enterprise and features

Introduction

Since industry is a loose concept and it can be of various types (manufacturing and mining, light and heavy, large and small), it is simply unrealistic to touch upon business ideas from each industry in one article. Therefore, this article will consider several business ideas for light industry, built on the production of something.

Industrial business idea - package production

Well, first of all, I would like to highlight the fact that packages are always in demand, since absolutely all people on this earth use them. And demand, as you probably all know, is the first sign of a successful business.

The demand is clear, let's define the equipment. Do you really need a small investment to organize this business? Nowadays there are many different equipment for the production of bags. The simplest equipment costs about 320,000 rubles, but now a complete set of the package production line costs about 780,000 rubles. As you have seen, the investments in this business are actually not large, and they will pay off very quickly, because, as noted above, the demand for these products is very high.

In order for the business to quickly go up the hill and give good income, it is better to think about purchasing several machines for making various bags (plastic, T-shirts, garbage, with logos, and so on). For the manufacture of each type of bag you need your own equipment. The larger your business, the more equipment you need. Of course, it all depends on your capabilities.

And now about the possible income. Let's say you have purchased the simplest equipment worth 320,000 rubles, the productivity of which is about 40 bags per minute. One packet costs 50 kopecks at a cost price of 10 kopecks. The profit from one bag is 40 kopecks. In an 11-hour working day, the machine can produce approximately 26,400 bags. In total, the daily net profit will be equal to 10,560 rubles, and for a week (6 days) - 63,360 rubles. If we subtract monthly expenses, then the net profit per month will be about 50,000 rubles. Is it profit from one machine if there are several?

Industrial business idea - pasta production

The very first step in organizing such a business should be to assess the market for this product in your city. If the competition is small, then you can safely proceed to further actions, otherwise you will need to study the products of your competitors to improve the quality of your future products, in other words, you should, if possible, correct all the mistakes and shortcomings of competitors in your business.

Next, you will need to decide on the location. It should be of such an area that there would be enough space for equipment and a small space for raw materials and products. On average, you need a space of 100. The premises can be purchased or rented, you can already see this according to your possibilities.

Industrial business ideas

Printed circuit boards are the electronic heart of any modern gadget. It is a dielectric plate with electrical conducting circuits deposited on the surface of this plate, or embedded inside it. All electronic components are connected with the help of printed circuit boards. To do this, the pins of the components are soldered to the board to the mounting pads or holes, and due to the pattern of the electrical conductive circuits, the components interact with each other.

Usually, the conductive pattern on the board is made of foil, and the base itself - a dielectric plate - is made of fiberglass, getinax. Printed circuit boards are divided into one-sided OPP (foil on one side), double-sided DPP (foil on both sides), multilayer MPP (obtained by gluing several OPP or DPP together, in such a way that several conductive layers with their own pattern are placed inside the dielectric plate) ... OPP is in the greatest demand due to its ease of manufacture and wide application possibilities. DPP is used less often, since their manufacture is several times more expensive, and the efficiency, in comparison with OPP, is not so high. MPP is used in expensive and compact devices; it is practically not used in everyday life and small-scale production.

All sheet materials from which the printed circuit boards are made are marked with the alphanumeric index FR (flame resistant). The numbers from 1 to 5 after the letters indicate the quality of the material.

FR-1, FR-2, FR-3 - paper impregnated with epoxy special compounds. FR-4, FR-5 - fiberglass and epoxy composite. In practice, FR-1, due to its low performance and fear of moisture, is not used. However, it is extremely cheap and is often used to make working prototypes of printed circuit boards with a short life cycle. FR-2 is an inexpensive, reliable and high-quality dielectric; boards made of this material are widely used in the manufacture of household appliances and large-scale production of printed circuit boards. FR-4 is used in the production of industrial equipment and small-scale (piece) manufacturing of PCBs.

The fundamental methods of manufacturing printed circuit boards can be divided into two large types - additive (from the Latin additio - addition) and subtractive (from the Latin subtratio - subtraction). In the first case, an electrically conductive pattern is formed in various ways on the basis of the future printed circuit board (usually by a chemical method) through a special mask. In the second case, a sheet foil is applied to the dielectric plate, then, a mask of the future circuit is formed on top of it, and unnecessary foil sections are removed using various methods (laser, chemical etching, mechanical removal).

In industrial production, combined methods are usually used. Thus, minimization of the production cost of printed circuit boards is achieved. Also, with the progress in the use of laser technology, industrial laser prototyping machines are increasingly used.

But no matter what installation is chosen for organizing your own business, they are all highly automated and human participation in the process of manufacturing printed circuit boards is reduced to monitoring the parameters of the installation and their timely correction.

The post-processing is the same for boards produced in any way - this is an electrical test (checking all contact pads and drawing for conductivity), applying a solder mask and marking.

To expand your business, you can master the installation supervision of components on printed circuit boards and the production of technical documentation, which allows customers to receive a completely finished product.

The minimum area for opening a production or a workshop for the production of printed circuit boards is 80 m², excluding warehouse space. Most equipment requires a 380V three-phase power supply, and chemical equipment, where active solutions are drained, requires the use of special sewage drains. Therefore, it is more expedient to open a similar production in industrial clusters or zones.
