Main Advantages of BGA Assembly in PCBMay
What is BGA Assembly
The Ball Grid Array or BGA is one of the encapsulation methods used to connect components in integrated circuits.With a large number of pins,the BGA Assembly makes the connection by welding small balls with direct fixation between component and plate.
It is one of the most critical encapsulations of the process and requires extra care during assembly,as without the aid of radiological equipment,it is possible to inspect only the external balls of the component.
BGA Assembly Technique
This type of technique is fundamental in small size cards,such as microchips for cell phones or devices attached to IoT equipment,such as smart clothes,or example.For this size of frame,Quad Flat Pack (QFP) technology is not as efficient.
The BGA Assembly allows a greater number of connections with extreme precision.As the connections are in the component and not in terminals,this type of technology has stood out as the best alternative to aggregate multiple functions in tiny plates.
In this way,with the terminals under the component,no side area,other than that corresponding to the component itself,is occupied on the printed circuit board.
BGA Assembly: Essential Care for Successful Assembly
Good practices for the use of techniques and equipment are fundamental for the success of the assembly.We already talked here on the blog,for example,about choosing the right equipment,which can interfere with the speed and accuracy of the assembly.
We also address the importance of having well-aligned processes and clear communication through the process sheet,among other good practices.So,with BGA it couldn’t be different.However,for BGA Assembly to be carried out successfully,some extra care is still necessary. Check out:
Component Storage and Handling Precautions
Each and every component for the assembly of electronic boards requires care.However,some of them have special needs,which must be observed in the component packaging at the time of purchase and strictly respected until the product leaves the factory.
Most components are fragile and sensitive to moisture and when it comes to mounting BGA even more.When the size of the plate in question is reduced,extra care is also taken in relation to handling,so that there is no loss and material management.
It is recommended that the industry or the specialized assembler that will handle these components,have the necessary expertise and use the right equipment and procedures for the handling and management of inputs. Otherwise,some losses can result in damage to the continuity of the BGA Assembly line,occasional delays or unnecessary losses.
Choice of Equipment in BGA Assembly
The BGA assembly,as it is more sensitive, must have extremely precise equipment for applying paste. Otherwise,you will not reach all the necessary points.
Stencil – A stencil in poor condition or with poor material can ruin all BGA solder paste application planning.The IPC7525 standard defines parameters that ensure quality in the application,stay tuned to it.
Support – some solder paste application errors occur simply due to an error in the support of the plate in the equipment.Make sure that the base guarantees the application in all points of the plate. For large BGA Assembly batches,it is even recommended to make a support dedicated to the specific plate.
Paste quality – The good application of solder paste requires that the product is in perfect conditions of use, within validity and with normal texture conditions.It is necessary to homogenize the product from time to time so that the bottom is no longer concentrated and impairs the application.
Stencil cleaning – in addition to taking care of the paste itself, also take care of cleaning the stencil. Large batches need maintenance from time to time on the equipment used. Otherwise, the application quality of the first board will not be the same as the last.
Care in the Inspection of Solder Paste
Because it is so important for the operation of the plate, the application of the solder paste requires further inspection. Therefore, SPI equipment is essential to allow a complete verification of displacement, height, volume, insufficiency, etc.
Only then will the plate be able to follow the course of the production line without problems. If this step is skipped, it is possible that some errors will go unnoticed and the plaque will only be identified as inconsistent at the end of the process.
Worse, it may be that the problem did not occur on just one, but on several cards. In this case, the error can be irreversible and the losses much greater.
Care in the Insertion Stage
The insertion of components using the BGA assembly technique needs to be done by specific equipment. The chosen inserter must be extremely precise, due to the small distance between balls that require perfect centralization of the component.
The technology of plate assembly has reached the point that human hands and eyes are not able to achieve the precision required in such small sizes. Not to mention that, in such a small space for multiple functions, a micrometric displacement can compromise the final disposition of the other components on the plate.
Care in the Remelting Stage
Every electro-electronic assembly that passes through the remelting oven requires the “sacrifice” of a plate. In this way, it will be possible to carry out a thermal profile of the remelting furnace that takes into account the characteristics of the plate and the components, ensuring a quality weld.
If this is not done, when passing through the oven, the other plates may be overheated, or underheated, and may not have as much quality as necessary, or even need to be discarded.
BGA Rework Station
Another important point is that if there is a need to exchange or assemble with the other components already welded to a BGA component, specific equipment, called a BGA rework station, is required. It is equipment that also needs a specific thermal profile that guarantees a quality weld.
How to Choose an Assembler Suitable for the BGA Assembly
Considering the advantages and the high number of items that must be taken into account in the BGA assembly,you must be wondering if it is really worth it.PCBMay is your best choice.
Thus,it becomes much more advantageous to hire an outsourced assembler, especially if it is in the form of total outsourcing.In this way,each of the stages,care and tests is under the contractor’s responsibility and your company receives the ready,well-finished and perfect plate to be inserted in the equipment in question.
