Before BGAs can be re-used, their solder balls have to be replaced. All Martin’s rework stations can be used to carry this out by using additional mini ovens.
Now, with Martin's new Set Reball-03.1 the proven Martin Reballing Technology is now also available with a convenient and cost effective standalone unit. One of the advantages is the fact that just this one set is needed to deal with the most diverse range of BGAs. Each process takes only about three minutes, says Martin.
The new easy-to-use BGA reballer is also suitable for QFNs and CSPs.
Economic reball solution
In order to restore a removed BGA to be a fully functioning component a number of suitable utensils used to be required: a stencil of the correct size and ball pitch, a mini oven of the appropriate size and a hot air pen with control unit.
According to Martin, the Set Reball-03.1 works out significantly more economically: users save on not having to acquire several Mini Ovens and suitable stencils. The Hot-Reball-03 unit comes with a BGA holder, seven adapters and stencils for customisation with 'Kapton' tape. This reduces the cost by 50% compared with previous arrangements and offers a very economical solution especially for companies with limited budgets and varying applications.
With the aid of the 'Teach' function, the equipment automatically calculates the duration of the reballing process. At the touch of a few buttons: selection of process temperature and program number, insertion of prepared BGA, lid closed, Start etc. By employing the SMD hook through an opening the user can establish the melting point and signal this with pressing the Stop button. The control automatically calculates any extra time required for a reliable solder connection and stores all data in one of the 11 programs for repeat operations. The lid of Hot-Reball-03 then automatically opens and cooling starts with the integrated fan. The BGA is ready for re-use.
The Set Reball-03.1 is now available with a comprehensive range of accessories and consumables, such as Reballing Holder, seven Adapters for BGAs sizes from 15 to 45 mm, Teach Function and both stencils for 1,27 mm pitch.
