PCB Assembly Process

At Cesgate Electronics, we pride ourselves on our efficient and high-quality turnkey PCB assembly service. Cesgate employs a number of strategies in Quality Management and process control to ensure that every PCB order is done right the first time. In order to achieve the fastest possible turnaround of the highest quality product, we continuously strive to improve our services and to make each step as efficient as possible.

This article provides a step-by-step overview of the standard turnkey PCB assembly process, providing key information at each stage that might relate to a client’s interest. This is a brief overview only, and for those interested in a more detailed elaboration around Cesgate ’s specific capabilities, we recommend reading our comprehensive DFM Guidelines and DFA Guidelines documents.

One of the most important factors in the overall efficiency of each PCB assembly project is the client’s understanding of Cesgate’s process. The number of steps involved in the PCB assembly process depends upon the specific nature of the project in question, as illustrated by the flowchart below, and each of these steps is explained briefly in the following sections. For simplicity’s sake, some intermediary stages are not shown in this flowchart; for example, each stage includes individual inspection upon completion. Being familiar with this process in advance, a savvy engineer can design their PCB specifically for a fast and efficient assembly process by minimizing the overall number of steps required.

Reflow Soldering


With parts mounted securely in place with solder paste underneath their pads, it is time for the PCBs to enter the reflow soldering phase. This is the most common method for PCB assembly in the industry today since it is much more flexible in terms of PCB layout requirements compared with wave or manual soldering. Most of the time, Cesgate can use reflow soldering for a majority of the components on a board, and then pass the mostly-assembled boards to our highly skilled manual soldering team for the final few connectors.

For double-sided SMT projects, the boards will need to be reflowed once for each side. A special adhesive is applied underneath the components that were soldered in the first run to prevent them from detaching and falling off the board when their solder is re-heated.

The main concern in reflow soldering is that components must withstand high levels of heat for a more prolonged period of time than what would be required for either wave or manual soldering. The vast majority of modern SMT components are designed with these heat profiles in mind, but many through-hole components are not suited to reflow soldering for this reason. Cesgate’s standard reflow cycle is described by the graph below.

Main PCBA Application - Multilayer Board

Multi-layer board: The required circuits are made on the front and back surfaces of multiple double-sided boards, and an insulating layer (Prepreg) is sandwiched between the two double-sided boards and then pressed together to form several layers of copper. The construction of the wire is usually an even number of layers due to the use of multiple double-sided laminates. The number of copper wires that can be made by multi-layer boards is the largest, and it is used in more complex circuits. At present, the motherboards used in computers mostly use eight-layer boards because of too many components. Generally, small electronic products, such as mobile phones, tablet computers, etc. Due to the requirement of small size, at least an eight-layer board is required. The more electronic components, the smaller the product size, and usually more layers of Main PCBA are required.

1. Material
FR-4 (glass fiber epoxy resin substrate) is the most widely used material in the global electronics industry. FR is a code name for a flame-resistant material grade, which means a material specification that the resin material must be able to self-extinguish after burning. It is not a material name, but a material grade, so there are many types of FR-4 grade materials currently used in general circuit boards, but most of them are four-functional epoxy resin plus filler (Filler) and glass fiber. The composite material made. In recent years, due to the development of electronic product installation technology and Main PCBA technology, FR-4 products with high Tg have appeared again. Tg degree (glass transition temperature - Glass Transition Temperature)
