PCB基板の銅めっき発泡の5大原因

5 Major Causes of Foaming on Copper Plating of a PCB Board There are many causes of foaming on the copper plating of a PCB board. Some are caused by oil or dust pollution while others are caused by the copper sinking process. Foaming is a problem with any copper plating process as it requires chemical solutions that can cross-contaminate other areas. It can also occur due to improper local treatment of the board surface. Micro-etching In micro-etching, the activity of the copper precipitate is too strong, causing pores to leak and blisters. It can also lead to poor adhesion and deteriorate coating quality. Hence, removing these impurities is crucial […]

高品質PCBめっき穴の4つの主要工程

4 Main Processes For Making High Quality PCB Plated Though Holes Printed circuit boards (PCBs) are the heart of any electrical device, and the quality of their played through holes will directly impact the final product. Without proper quality control, a board might not meet the expected standards, and it may even have to be scrapped, which will cost a lot of money. Therefore, it is essential to have high-quality PCB processing equipment. Solder resist PCB plated though holes are used in a variety of applications. They are conductive and have lower resistance than non-plated through holes. They are also more mechanically stable. PCBs are typically double-sided and have multiple […]

PCBを外から観察する方法

How to Observe PCBs From the Outside Observing the pcb from the outside makes it easy to identify defects in the outer layers. It’s also easy to spot the effects of not enough gap between the components when looking at the board from the outside. Observing a pcb from the outside can easily identify defects in the outer layers Observing a PCB from the outside can help you spot defects in the outer layers of the circuit board. It is easier to identify these defects than they are to spot inside. PCBs are typically green in color, and they have copper traces and soldermask that make them easily recognizable. Depending […]

ソルダーマスクとは?

What is Solder Mask? In the electronic manufacturing industry, solder masks are used to help ensure a successful soldering process. These masks are commonly green in color, and their fine-tuned formulations allow manufacturers to maximize their performance. The masks must adhere to the PCB laminate to achieve optimum performance. Good adhesion allows masks to print narrow dams between tight SMD pads. Green solder masks also respond well to UV exposure, which helps cure them for optimal performance. Process of applying solder mask to a circuit board The process of applying solder mask to a circuit boards has many steps, including pretreatment, coating, drying, prebaking, registration, exposure, developing, final curing, and […]

Ceramic PCB Vs Metal Core PCB

Ceramic PCB Vs Metal Core PCB Ceramic pcbs are more thermally efficient than their metal counterparts. This means that the operating temperature of a PCB will be lower. Aluminum PCBs, on the other hand, will be subject to a dielectric layer, while ceramic PCBs will not. In addition, ceramic PCBs are more durable than their metal counterparts. FR4 vs ceramic pcb The main difference between FR4 PCB and ceramic PCB is their thermal conductivity performance. FR4 PCB is prone to high thermal conductivity while ceramic PCB is prone to low thermal conductivity. Ceramic PCBs are better for applications that need high thermal conductivity. However, they are more expensive. FR4 PCB […]

How to Determine the Number of Layers in PCBs

How to Determine the Number of Layers in PCBs Before deciding on the number of layers for a PCB, it is essential to identify the purpose for which the PCB will be used. This will affect the number of layers required, as will the complexity of the electronic circuit and the amount of power it will consume. Generally speaking, high-tech applications require a high number of layers. Using the signal layer estimator PCB layer count estimation is a crucial step in board manufacturing. The more layers a circuit board has, the more expensive it will be. More layers also require more production steps, materials, and time. Using the signal layer […]

The Difference Between FPGA and CPLD

The Difference Between FPGA and CPLD The two types of programmable logic chips are the Field Programmable Gate Array (FPGA) and the Complex Programmable Logic Device (CPLD). The former is a “fine-grain” device, whereas the latter is based on larger blocks. The two types have different strengths and weaknesses. While FPGAs are better for simple applications, CPLDs are ideal for complex algorithms. CPLD is a programmable ASIC device A CPLD is a programmable IC device that is composed of a macrocell. The macrocell contains AND arrays and flip-flops, which complete the combinational logic function. The AND array generates a product term, which is the output of the CPLD. The product […]

Advantages and Disadvantages of PCB Surface Finishes

Advantages and Disadvantages of PCB Surface Finishes Surface finishes can be classified in many different ways. This article discusses the main attributes of PCB surface finishes and the requirements of various types of PCB products. The benefits and disadvantages of each type are discussed. To determine the right surface finish for your PCB project, you can refer to the following table. ENTEC 106(r) Among the most widely used surface finishes in the PCB industry is ENEPIG. It is a two-layer metallic coating consisting of 2-8 min Au over 120-240 min Ni. The nickel acts as a barrier for the copper on the PCB surface. Gold protects the nickel from corrosion […]

Why Flexible PCB Need Stiffeners

Why Flexible PCB Need Stiffeners A PCB stiffener is required to give your PCB its rigidity. There are several materials available to stiffen PCBs. Some are more expensive than others, such as FR4 or stainless steel. You need to decide which type is best for your specific needs. Stainless steel Flexible printed circuit boards (PCBs) are among the most popular types of PCBs on the market today. Their flexibility allows designers to design circuitry that isn’t possible with rigid circuits. However, a flexible PCB’s lack of stiffness can lead to performance and durability issues. For this reason, flexible PCBs often include stainless steel stiffeners. A stiffener may be either thick […]
