    What Are The Main Differences Between OEM And EMS PCB?

    In the arena of PCB manufacturing, OEM (Original Equipment Manufacturing) and EMS are very popular terms. Both of these PCB manufacturing services have core differences in some cases. Now, we are going to focus on the comparison between these two.

    Operation

    OEM is also known as contract manufacturing in the PCB industry. OEM PCB is designed and produced according to the consumer’s specifications. In contrast, PCB EMS deals with designing, manufacturing, assembly testing, etc.

    EMS also takes care of other sectors related to the fabrication, repairing, distribution of electronic products. That means an EMS PCB provider delivers original equipment manufacturing (OEM) as well. So, EMS renders controlled and smooth PCB manufacturing compared to OEM.

    PCB Assembly

    OEM PCB is supportive of surface mount technology (SMT) in most cases. That’s why it has some limitations in different electronic devices. But, EMS allows both SMT and THT (Through-hole Technology) in PCB assembly.

    Besides, the components used in EMS PCBA are easy to program and replace. So, PCB electronic manufacturing offers higher flexibility to the designer.

    Expertise Of Design Testing

    Experience makes a huge difference in the PCB industry. EMS shows impressive expertise in the case of PCB assembly testing. The technicians who conduct all segments of electronic manufacturing are more experienced than OEM PCB technicians.

    Cost Performance

    OEM PCB deals with limited issues compared to EMS. So, it is less expensive in terms of manufacturing cost. On the contrary, EMS circuit boards have cost-effective features. Again, PCB quick-turn EMS offers a low production time and superb performance. So, you don’t need to be worried about its high expense.

    Application Range

    EMS PCB has versatile applications in countless sectors. Its easy assembly and competitive cost performance make it compatible with a vast range of applications. But, OEM PCBs are not widely used in electronic components.

    Product Quality

    PCB EMS never trades off quality with any other property. Its high-quality assembly and fabrication with proper inspection lift the product to a high standard.

    We produce EMS circuit boards made of high-level raw materials. Our products are also certified by UL. Inquire us immediately to enjoy the most elite PCB manufacturing service.

    What Are The Component Mounting Processes In EMS PCB?

    EMS PCB supports two types of component mounting during the assembly.

    Surface Mount Technology (SMT)

    In this mounting process, surface mount devices are used. This is the most popular component mounting in the electronic assembly. SMD is supportive of small-size PCB designs.

    So, you should apply the necessary equipment to achieve desired design accuracy. Besides, SMDs are effective for ensuring high-speed data propagation. It is easier for the designer to arrange the components concerning the design in the case of SMT.

    That means SMT is the perfect choice for compact EMS circuit board design. Watch this video to know more about SMT:

    Through-hole Technology (THT)

    It deals with pin-through-hole (PTH) components. Here, the terminals of the PCB components are placed into the holes. Then, you need to weld these components from the other side of the circuit board.

    So, you can consider THT as a manual process. It provides sufficient robustness in the PCB design. But, this mounting process is less utilized in electronic manufacturing due to its high expense and time consumption.

    What Are The Common Reasons For Occurring Failure Modes In EMS PCB?

    Improper execution of EMS manufacturing services causes different failure modes in EMS PCB assembly. Here, some common reasons for PCB EMS failures are explained so that you will be aware of these modes during manufacturing.

    Layer Misalignment

    EMS Multilayer PCBs are supremely effective in modern electronic projects. But, you don’t expect a high-class performance from a design where layers are misaligned. Misalignment causes a malfunction in the circuit board.

    Again, it increases the possibility of occurring short circuits, poor signal transmission, etc.

    Improper Etching

    Etching is a mandatory part of the PCB EMS fabrication. It eliminates unwanted copper from the PCB traces. But, improper etching causes serious damage to the PCB. Like a highly toxic etching solution can etch necessary copper and other PCB portions. Then, EMS PCB can’t deliver maximum output.

    Metallic Corrosion

    Poor solder flux causes decay of metals used in the PCB fabrication. If you don’t apply solder flux properly during electronic assembly, metallic corrosion will be a very common failure mode.

    Wrong Copper Thickness

    Well-calculated copper thicknesses improve the current carrying capacity in circuit boards having electronic manufacturing services. But, the wrong copper weight can’t handle higher current loads that result in overheating and burning issues.

    Component Damaging

    When the PCB components are exposed to moisture, they get damaged due to oxidation. Improper component packaging also causes failure in the PCB EMS.

    Poor Solder Connection

    Excessive thermal pressures and wrong use of solder can break the solder connections. Then, the PCB can’t function properly because of having any smooth connection between the components and circuit board.

    EMS PCB Common Failures

    EMS PCB Common Failures

    These are the common reasons for having failure modes in EMS PCB assembly. You should ensure a well-designed PCB layout and proper execution of assembly. Then, there will be fewer possibilities of facing such problems.

    Is Multilayer Stackup Suitable In EMS PCB Assembly?

    Yes. EMS PCB supports multilayer stackup from 4 to 40 layers. This PCB ensures superb thermal management and layer alignment in multilayer designs. So, it can deliver the optimum output in signal transmission systems.

    The dielectric materials used in multilayer EMS PCB are highly effective for maintaining high dielectric strength. Besides, these components offer a low relative permittivity in different PCB layers.
