BEST Inc. is a company known for offering top-quality PCB repair and rework services. It is composed of highly trained IPC-certified soldering technicians who can perform the most complex BGA repair and PCB rework. They use state-of-the-art equipment to ensure that the rework they have performed on clients' PCBs and BGAs will be done correctly. The company also offers advisory services that involve empowering clients on how to more quickly and effectively rework and repair their printed circuit boards on their own. They also sell the materials and tools necessary for the PCB rework.Answering a query, the company's spokesperson said, "One of the critical components of the PCB rework process is the stencil. A PCB rework stencil is a thin, flat sheet of material made of stainless steel or polyimide that has a pattern of holes or apertures cut into it. These apertures correspond to the pads on the PCB. It is used to apply solder paste to these areas during the rework process."
In need of a BGA rework stencil? BEST Inc. offers a unique stenciling BGA rework stencil system. It is configurable, meaning that one doesn't have to sort through all of the patterns that are commonly used. As a result, it improves first yields and repairs solder masks that may have been damaged removing the device. The BGA rework stencil costs less, and it comes in three thicknesses, which are 0.008", 0.006", and 0.004. On purchase, clients need to send BEST information about what the BGA stencil should have, such as overall package size, the pattern of the solder array dimensions, ball size, and more. The company accepts either standard Gerber files, part data sheets, or CAD files to design and fabricate the BGA stencil. Typically, upon shipment, the stencils are packaged in groups of 10 in a small anti-static bag.
The company’s spokesperson added, "The stencil typically ensures that the proper amount of solder paste is applied uniformly to the PCB. This reduces the risk of defects such as shorts, opens, and tombstoning. As a result, it makes the rework process more efficient, accurate, and cost-effective, ensuring the PCBs are repaired to the highest quality and performance standards."
Clients can also count on BEST Inc. to get a “gently used” IPC 620 standard requirement standard document, revision C. It is the latest revision of the only industry-consensus standard for acceptance and requirements of cable and wire harness assemblies. It includes new sections for safety cable, safety wiring, grommets, and raceways, along with updated information across many of the sections. With more than 700 photographs and illustrations, this standard describes methods, materials, tests, and acceptance criteria for producing crimped, mechanically secured, soldered interconnections and the various related assembly activities associated with cable and harness assemblies. Though the standard offered is used, BEST Inc ensures that they are in fair condition and are not written on. However, there may be some imperfections on the front or back covers due to normal use.
