The iPhone 7 and 7 Plus represent a pivotal era in mobile engineering, marking the shift toward more complex power management and the introduction of the A10 Fusion chip. For technicians performing board-level repairs—such as IC reballing or CPU swaps—having a precise BGA (Ball Grid Array) stencil is non-negotiable. 7/ 7 plus BGA STENCIL-Original
Original-spec stencils are typically crafted from high-grade Japanese stainless steel and utilize laser-cut square holes rather than circular ones to ensure easier tin paste release and uniform solder ball height.
Technical Overview: The 7 / 7 Plus Logic Board
The logic board for these devices is densely packed. A “Full Specification” stencil must account for the primary SoC (System on Chip), NAND flash memory, and the myriad of smaller power, audio, and RF chips that frequently fail due to “audio disease” or thermal stress.

Key Features of “Original Specification” Stencils
When sourcing a “Full Specification” stencil for the iPhone 7 series, look for these three hallmark features that distinguish professional tools from generic alternatives:
1. Heat-Resistant Alloy (Anti-Warp)
Original-grade stencils use a specific blend of stainless steel (often 301 or 304 series) that has been chemically etched or laser-treated to resist “bulging.” Since reballing requires temperatures between 280°C and 350°C, a low-quality stencil will warp, causing solder bridges.
2. Precise Hole Alignment (CNC Laser)
The holes are not just punched; they are laser-drilled with a slight conical taper. This means the hole on the bottom (touching the chip) is slightly wider than the top. This allows the solder paste to slide out cleanly when the stencil is lifted.
3. Integrated IC Positioning
High-end stencils often feature “grooves” or “steps” etched into the steel. These allow the IC to “snap” into place, ensuring the pins are perfectly centered under the holes without needing manual alignment under a microscope. 7/ 7 plus BGA STENCIL-Original
Common Reballing Scenarios for iPhone 7/7 Plus
-
Audio IC Repair: Due to the “Loop Disease” (where the phone hangs on the Apple logo or the voice memo icon is grayed out), the 338S00105 chip often needs to be pulled, the pads on the board jumped, and the chip reballed. 7/ 7 plus BGA STENCIL-Original
-
Baseband Issues: If the device shows “No Service” or “Searching,” the Baseband PMU or the Baseband CPU itself may have fractured solder joints. 7/ 7 plus BGA STENCIL-Original
-
NAND Upgrades: For users increasing storage from 32GB to 128GB or 256GB, the NAND stencil is used to prep the new high-capacity chip. 7/ 7 plus BGA STENCIL-Original
Maintenance and Usage Tips
To keep your iPhone 7/7 Plus stencil in “Original” condition:
-
Cleaning: Use 99% Isopropyl Alcohol (IPA) and a soft-bristled ESD brush after every use. Never let solder paste dry inside the holes.
-
Solder Paste: Use a high-quality “No-Clean” leaded solder paste (e.g., Sn63/Pb37) with a melting point of 183°C for the best results.
-
Pressure: Apply even pressure with tweezers in the center of the chip while heating to prevent “ghosting” or solder balls popping out of the holes.
