BGA Assembly


Our experienced engineering team is proficient in BGA (Ball Grid Array) assembly process along with X-ray inspections. We are confident of building a high-quality and good yield rate BGA assembly boards by following the right procedures. We start the process by creating a BGA prototype and help the customer to reduce unnecessary costs and turnaround times. Whether you need metal-core BGA or plastic or ceramic ones, we can get that to you in the shortest time.

BGA PCB Assembly

BGA Soldering

As we use the solder reflow process for soldering BGA onto the circuit board, we follow all the precautions to ensure good soldering techniques. We make sure to apply sufficient heat to ensure that all the balls are melted sufficiently and a strong bond is established. We also try to maintain the optimum temperature and prevent the solder balls from short-circuiting. If you are worried about the quality, we make sure to pay attention to the composition of the solder alloy, and the right temperatures are applied to keep the solder in the desired semi-liquid state.

BGA Assembly Service


At Mer-Mar Electronics, we have the capabilities to take on BGA rework and reballing for different types of land grid array packages like plastic BGA, chip BGA, ceramic column grid array. We help you restore your BGAs to their original performance and quality with solution-driven rework and reballing services. We correct any defects in the device, fix the solder joints, or oversights during the upgrade process during the BGA rework process. With comprehensive BGA reballing services, we maintain the efficacy of the SMT boards.

BGA Assembly Families

Mer-Mar Electronics is one of the leading companies in BGA assembly and has experience with all the three BGA assembly family types like PBGA (plastic BGA), TBGA (tape BGA), and CBGA (ceramic BGA). Whether you need lead or lead-free solder balls, you are at the right place! We use a variety of subtypes based on the substrate and packaging materials for creating custom designs and connecting the packages to the circuit board.

BGA PCB Assembly Service


Our fine engineering team is constantly working on fine pitch BGAs and putting extra effort to reduce the board costs. We assemble fine pitch BGAs for many devices like mobile phones, notebook mainboards, etc. We identify the root causes of the BGA defects like solder joint cracks. We perform a variety of tests to create flawless BGA fine pitches that can steadily move into next-generation products.

BGA Assembly Services


With proper quality controls and inspection methods, we ensure to provide the BGA Assemblies with zero defects before it is shipped. We deploy a 3D X-ray inspection process for eliminating soldering problems like solder bridging and insufficient ball melting. We also add additional inspection layers to get the BGA profile correct. We assure you of excellent quality and reliable BGA assembly boards.

BGA (Ball Grid Array) Assembly Testing Capabilities

Mer-Mar Electronics is doing its best to make sure you achieve the level of optimization and reliability required. We use Surface Mount Technology (SMT) inspection or BGA inspection to analyze the chip-PCB connections. We constantly monitor various aspects of the assembly using a variety of inspection techniques like

  • Optical Inspection
  • Mechanical Inspection
  • X-ray Inspection

Optical Inspection – We closely view the ball grid array connections with the surface of the PCB using the proper equipment like an endoscope. We have deployed efficient personnel and employed the equipment for optical inspection in the market for assessing the quality of the assembly process.

Mechanical Testing – This is done through shock tests in which the full assembly is subjected to shock. The mechanical properties of the solder joints are evaluated by looking at and measuring the strain.

X-ray Inspection – We have adopted this most advanced method of BGA testing to get a clear picture of the entire process. Under the X-ray test, we see clearly the ball grid image where we visually analyze the connections that usually cannot be optically inspected. We constantly inspect the joints and monitor the quality. We make sure there are no alignment issues and the ball grid array connections are symmetrical.

BGA PCB Assembly Techniques

Mer-Mar Electronics is capable of ensuring SMT quality and decrease assembly defects. With modern manufacturing methods, we have been providing the SMT assembly process of BGA components for all volume production.

Surface Mount technology –Before we go for the assembly process, we make sure all the components go through the preheat treatment to make sure that they are sensitive to humidity and high temperatures. Before proceeding to the mounting of components, eliminate the moisture. We are skilled in solder paste printing, and solder paste is easily printed on the BGA components. Our engineers are skilled in both horizontal and vertical printing.

BGA SMT Soldering –We mount the components with high precision and even under heavy vibrations, they remain unfazed. We have a specialized SMT assembly line containing chip mounter on & offline AOI equipment, reflow soldering oven, solder paste printer, BGA rework station, etc. We provide a solid foundation for the BGA assembly boards and live up to the customer expectations.
