What are the precautions in the production of PCBA samples
At present, almost every company that does PCBA sample production is vigorously producing under the pressure of huge chip gap. With the upgrading and transformation of the national economy, more and more companies are appearing, but it is undeniable that most companies are still doing Facing huge financial pressure and technical difficulties, it is no easy task to make your products more distinctive and outstanding. It requires a lot of investment in capital, manpower, and technology.

So, what are the difficulties in making PCBA samples? The person in charge of Dongguan Boyuan Electronics Co., Ltd. pointed out that if it is a small order, many manufacturers are unwilling to take the order. After all, large quantities and small quantities are inseparable from start-up fees and engineering costs, but Boyuan Electronics has been established since its inception. It is our responsibility to solve the customer’s problems and strive to make every order, regardless of the size of the order, even if it is only PCBA sample production, it will be completed within the specified time according to the customer's requirements.

What are the precautions during the production of PCBA samples? Below, Boyuan Electronics will give you a general explanation:

The first point: patch processing. What is patch processing? The purpose is mostly to accurately install the surface components on the fixed position of the PCBA. Due to the strict environmental requirements during the patch processing, the relevant operators are not allowed to eat, drink, smoke, or place irrelevant debris in the work area to ensure their work The cleanliness of the countertops brooks no delay.

The second point: It is necessary to check the static discharge workbench regularly. The purpose of this is to ensure the effective progress of the work. The most common dangers of EOS/ESD components are most likely to be inseparable from incorrect grounding or oxides. Therefore, the staff of Boyuan Electronics will be in Special protection should be given to the "three-wire" ground terminal connector. It is forbidden to stack PCBA, which will cause personal injury. Special brackets should be set on the assembly work surface and placed according to the type. Don’t look at the details. It is these inconspicuous details that determine the company. The fate of future development.

The third point: Take care when taking the soldering surface during PCBA sample production. What do you mean specifically? Boyuan Electronics tells you that it means that the welding surface cannot be taken with bare hands or fingers during the operation. It is necessary to know that the grease secreted by the fingers will easily cause the weldability of the surface to be reduced, and welding defects are more likely to occur. It is not conducive to the integrity of the components, and it will also affect the final product, resulting in a greatly reduced pass rate. It must also be used in the assembly area where gloves are required. This is very important. It is important to know that soiling can easily cause pollution. It is necessary to change gloves when needed.

The fourth point: The entire operation process of PCBA sample production is inseparable from the hands of the operator. Therefore, some skin care products or various silicone-containing detergents should not be applied when cleaning the hands, because doing so will cause PCBA sample production. There are problems with the weldability and adhesion of the coating on the surface of the product. Some friends may ask, is there no need to use detergent? Of course not, the best way is to use the company's specially equipped cleaning agent, and strictly follow these operating rules to ensure the quality of the final product, reduce the damage of parts, and ensure the reduction of costs.

What are the points to note during PCB sample production? The four points introduced above are only rough generalizations. At the time, PCBA sample preparation is a seemingly simple but complicated task. Naturally, all aspects must be considered, and this is directly the most portable way to protect the ultimate interests of customers. .
