PCBA processing workshop environment and personnel requirements

Workshop is the main artery of PCBA factory, most of the production and processing are carried out in the workshop. For a PCBA factory, the environment of the workshop and the quality of the staff are the key to show the cultivation and excellence of the company culture. So today, we will walk into the workshop and understand the requirements of PCBA processing on the workshop environment and personnel.

PCBA production equipment and SMT patch processing technology for PCBA processing have certain requirements on power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static, and accessories worn by production personnel. And the workshop environment is more inclined to be clean and tidy, in order to reduce the health hazards of oil and dust to workshop workers. At the same time, environmental protection and greening are the pursuit and goal of modern development, because environmental protection and greening can reduce or control the generation of pollution sources. The particles of visible material are relatively large, which mainly affects the visibility in the workshop, so that the operation of workers in the workshop and the supervision of managers are affected. At the same time, visible particles often greatly reduce the service life of air conditioning systems and equipment in the workshop.

PCBA processing to the workshop environment specific requirements

1. Temperature and humidity requirements

In order to the normal operation of the equipment, and the high standard requirements of the production process, the workshop environment temperature control at 23±3 degrees Celsius is the best, the relative humidity of 45%-70%RH is the best.

2, ventilation capacity

Reflow welding and wave soldering equipment have exhaust and flue gas emission requirements, exhaust fans should be configured according to the equipment requirements. For full hot blast stove, the minimum flow rate of exhaust duct is generally required to be 14-15m/min.

3, power requirements

The power supply voltage and power meet the requirements of PCBA processing equipment. Voltage stability, generally required single-phase AC220V (220±10%, 50/60Hz), three-phase AC380V (380±10%, 50/60Hz). If the power supply fails to meet the requirements, configure a stabilized power supply with the power greater than the device power consumption. The power supply of the SMT machine requires independent grounding, and the connection method of three-phase and five-wire system should be adopted in general. Because of the high running speed of the patch machine, it is easy to produce electromagnetic interference when connected with other equipment, which affects the normal operation and mounting accuracy of the patch machine.

4, electrostatic protection requirements

The IC and other precision electronic components involved in the production of PCBA are often easily damaged by static electricity, so static electricity protection is also very important. Usually, the personnel entering the workshop must wear anti-static work clothes, wear a good cap, shoes need to be covered, wear anti-static bracelet.

Workshop is the core of PCBA factory, and is also the "home" that most staff rely on. It is the factory's inescapable responsibility to ensure the health of staff. Regular training of workshop environment and staff requirements for small-batch PCBA proofing is an indispensable and important link.

2. How long does it take PCBA to quote?

A lot of friends to give the information immediately to quote, so in general, a complete PCBA processing quote how long it takes? These need to be calculated from the PCBA production and manufacturing including several links? As we all know, PCBA is a general term for circuit board assembly in China, including PCB board proofing, component procurement, SMT patch, and DIP component plug-in welding. Therefore, the link of quotation is composed of these three parts. Next, Shenzhen PCBA processing manufacturers to introduce the three parts of the PCBA quotation for how long?

PCBA quotation time analysis

1. PCB expense

This link quotation needs to use the information of the board and the board description file. If there is no lack of data, the data should be sorted out neatly. If there are some special processes, the costs need to be recalculated, plus other additional costs, and a complete quotation can be made on the same day. If there are other circumstances, the time may exceed this time.

2. SMT patch processing expenses

The main cost of this module is in the processing fee accounting. Generally, SMT processing is charged according to one point. For example, some relatively small components are charged according to one point of one component, and some are charged according to one point of one foot, but generally the components are not less than two feet. Therefore, the unit price of those according to a component and a point is usually higher than that of a foot. Therefore, when calculating, do not only look at the unit price, but also look at the overall accounting, to see which form will be more cost-effective. The evaluation time for this module is also not very long.

3. Component costs

Components are divided into two categories, conventional resistance capacitors and some more special components. The price of these components is relatively transparent in the market, and it is also relatively easy to evaluate the price. However, the price evaluation of some other special BGA and IC chips will be more troublesome, because many of these components will be affected by international embargo, strict approval process, long customs clearance time and price instability. The price of such components fluctuates greatly, so the quotation takes the longest time, at least about three to four days.

Through the above simple explanation, we can understand that the whole process of PCBA's latest quotation will take several days, excluding holidays. There is also a case that the enterprise itself and reserve materials can greatly shorten the time of the quotation. Among the three quotation modules, the quotation of PCB board and processing link is relatively fast. Only when the quotation of some special components is encountered, the quotation time will be relatively long. Secondly, the order quantity of some enterprises is relatively large, you need to queue up the offer, but also need to spend some time.
