High IO Count BGA Reballing Preform Simplifies Repair

ROLLING MEADOWS, Ill. - Sept. 15, 2020 - PRLog -- New Product: BEST Delivers 6,000 Ball Count Reballing Preform

BEST Inc. announces that it has begun shipping 6,000 ball count BGA preforms. BEST EZReball™ preforms are in their 8^th year of production and until recently the largest ball count consisted of 4,000 solder balls on a 0.4mm pitch over a 45mm x 45mm package. This latest product capability was the result of advanced laser processing of the preforms.

BEST EZReball™ soldering preforms can be ordered and built in a variety of configurations from 6 to now 6,000 plus balls. Sizes of the balls range from 10 to 40 mils in solder alloys of Sn63Pb37, SAC305 and Sn10Pb90. Each of the preforms is "made to order" onsite at BEST Inc. using laser machining to construct the preforms. Lead times for a single pack of (15) preforms are typically a few business days.

BGA reballing preforms (http://www.soldertools.net/new-reballing-pattern/) are used to assist in the rework of BGAs when the alloy of the device needs to be changed out or when performing reliability analysis for suspect devices that come back from the field. Reballing preforms are custom made per the original device pattern as they array the solder balls for lining up to the device solder ball pattern. Skilled soldering rework technicians can reball components in 10 minutes once they become familiar with the reballing method.

"As the IO count for server and cloud-based computing get larger and more complex we are constantly being challenged to create greater ball count reballing preforms," commented Dan Patten, general manager at BEST Inc.

BEST Inc. also provides reballing services to a variety of Class 2 and Class 3 electronic electronic assemblers, OEMs and others.
