HOW TO CHOOSING THE RIGHT PCB ASSEMBLY PROVIDER?
Since Q1, 2023 the electronic components market has experienced a high degree of unpredictable changes, with the supply of Printed Circuit Boards being no exception.
With the ongoing global pandemic which has sparked anxieties among the whole electronic manufacturing supply chain, finding the right PCB Manufacturing partner might become more challenging.
Here is a shortlist of what should be taken into consideration when seeking a new electronic manufacturing partner.
One of the most crucial factors when it comes to selecting the right partner is the financial aspects. However, it should not be the most important benchmark when making this decision for your business.
Choosing the right EMS partner for your PCB assembly is a complex process that refers to not only the documentation, and production but also the supply chain.
Purchasing PCB assemblies are a complicated process. Therefore, with the attention being focused on the determining factor, which is the final price of the product, you should also look at any potential hidden costs and their consequences for your budget.
If a supplier confirms a low price for a product but lacks strong manufacturing planning competencies, this can result in delays in delivery of your product and bring unnecessary additional costs.
Poorly developed planning may result in, inadequate manufactured products and this will spark an increase of complaints from your customers. As a result, you may not only potentially face additional expenses for various types of compensation, but more importantly, face costs that relate to your brand’s credibility.
Quality is an important concept when it comes to choosing the right PCB assembly provider for your business.
Quality of production, the PCB board and the service the supplier is providing all should be taking into consideration.
Production quality ensures; the correct dimensions, accurately placed components, minimal board warping and most importantly that the board passes all the tests.
The quality of service that the supplier provides is more complex. You should ensure that they are not only responsive but also agile. The providers should consistently produce your products to the required specifications.
New Product Introduction (NPI)
New Product Introduction that meets customer expectations is a complicated process, which requires the collection of reliable information as well as the dedication of time and resources of the entire company.
Your PCB provider must use a strategy or business model to implement new products. There are few key elements that PCB assembly suppliers should take into consideration while developing your product, these are as follows:
Status and Reporting
After following the process and the new product is established, your PCB providers must work on modifications and improvements. They should perform all the necessary tests and inspections to verify that the product is top quality.
Experience in the Industry
When it comes to PCB assembling; time and experience are essential. A well-developed PCB Assembly supplier takes years of practice; evolution, problem solving and technology.
Not only the experience of the organisation but also the experience of individuals involved in the key processes is important. A strong solid foundation will let the business react and adapt more effectively to any unexpected changes.
Therefore, experience in manufacturing or supply chain management is a desirable value when it comes to choosing the suitable PCB assembly provider for your business.
Price, Quality, NPI and Experience are all factors you should take into consideration as an electronic manufacturer when searching for an efficient, competitive and secure PCB Assembly provider.

Common quality defects in reflow soldering and improvement methods for tin bead improvement
Tin beads are similar to solder balls, but they are much smaller in size. Tin beads usually appear outside the solder pad due to various reasons before soldering, while they appear independently outside the solder pad and pins after soldering and fail to fuse with the solder paste, resulting in the formation of tin beads. Tin beads often appear on both sides of the component or between fine pitch pins, which can easily cause circuit board short circuits. The schematic diagram of tin bead quality defects is shown in the following figure.
Schematic diagram of tin bead quality defects
The reasons for the formation of tin beads
① Improper temperature setting in the heating zone of the reflow welding machine. If the preheating time is short and insufficient, the activity of the flux is low, and the oxide film on the surface of the solder pad and solder particles cannot be removed, which is easy to produce tin beads; If the preheating temperature is raised too quickly, the water vapor and solvent in the solder paste can easily vaporize and expand, resulting in the formation of tin beads.
② The corrosion accuracy of the opening size of the steel mesh does not meet the requirements, which can easily cause burrs in the opening size of the steel mesh, poor solder paste formation after printing, burrs or gaps; If the steel mesh is too thick or the printing pressure is too high, it is easy to cause the solder paste to accumulate too thick, which affects the quality of solder paste printing. When reflow soldering is carried out, these burrs or excessive solder paste can easily condense into solder beads.
③ The printed circuit board is not cleaned thoroughly, and there is residual solder paste. After reflow soldering at high temperatures, the residual solder paste is distributed around the solder pads. The solder paste near the solder pads and component solder ends is pulled back to the welding position to form solder joints, while the solder paste away from the solder pads and component solder ends gradually contracts towards the middle of the component, producing solder beads around or on the side of the component.
Process improvement methods for tin beads
Based on the above reasons analysis, the following process improvement methods are formulated:
① Control the preheating temperature of the preheating zone at 120-150 ℃, with a temperature increase rate of 1-4 ℃/s and a duration of about 90 seconds. Secondly, optimize the reflow soldering curve reasonably. With the continuous increase of temperature, the wettability of the solder paste is obvious, reducing the generation of solder beads. However, if the reflow soldering temperature is too high, it is easy to damage components, circuit boards, and solder pads. Therefore, choose an appropriate soldering temperature, and control the reflow temperature between 220-245 ℃.
② Re optimize the shape and center distance of the solder pad pattern, select appropriate steel mesh materials and processes, adjust the printing parameters of the printing machine, set the printing pressure reasonably, thereby improving the quality of solder paste printing and effectively reducing the formation of solder beads.
③ The circuit board for secondary printing needs to be cleaned with alcohol and blown with an air gun to remove residual solder paste on the circuit board. At the same time, production must strictly follow the production process requirements and standardize the operating process.

NEW ARRVIAL: Electronic PCB Assembly With 0.25mm Hole Size For Nuclear Detector
Due to the recent nuclear contaminated water incident in Japan, it is necessary to implement a detector that can monitor radiation data of imported food and cosmetics, So we developed a new PCBA product for nuclear detectors
The Tokyo Electric Power Company held an unscheduled press conference on the discharge of contaminated water from the Fukushima Daiichi nuclear power plant at around 10 am local time (9 am Beijing time) Monday, CCTV reported. At the meeting, Tepco announced that it would start discharging nuclear-contaminated water into the ocean at 1 p.m. local time on the same day (12 noon Beijing time today).
The Japanese government's decision has sparked widespread concern and controversy around the world. The waste water, accumulated after the 2011 Fukushima nuclear accident, contains a variety of dangerous substances, such as organic matter and radioactive isotopes. This decision has not only been strongly opposed by the public at home and abroad, but also triggered in-depth thinking and high attention to the nuclear radiation detection industry.
With the progress of modern science and technology, nuclear radiation detection technology has been continuously improved and enhanced, and has become an important part of evaluating the presence and level of radioactive materials. At present, the commonly used nuclear radiation detection methods include radioactive substance detectors, nuclear radiation sensors, nuclide separators, etc. These devices can accurately detect the type, quantity and intensity of radioactive substances and other information, providing strong technical support for the safety supervision of environmental protection, food, medical and other industries.
In addition to the nuclear sewage discharge incident in Japan, nuclear radiation detection technology has gradually been applied to more fields.
