Product Overview

The AMAOE Stencil-U-SCU1 (U-SCU1) is a high-precision, dedicated BGA (Ball Grid Array) reballing stencilfrom the patented UBGA-植锡专家系列 (UBGA – Solder Paste Expert Series). It is specifically designed for the professional repair and reballing of a wide range of Spreadtrum (now UNISOC) CPU and IC chips used primarily in budget and entry-level mobile devices. Its core purpose is to make the difficult reballing process simpler and more precise.

Key Features and Specifications

Model: Stencil-U-SCU1 / U-SCU1
Application: BGA Rework/Reballing for SPREADTRUM/UNISOC CPUs.
Material: High-quality steel mesh/stencil (often Japanese steel sheet).
Thickness: 0.12MM – The ideal thinness for precise solder ball formation.
Patented Design: ZL2016213989365
Special Feature: 散热孔防起鼓设计 (Heat dissipation hole anti-bulging design) – This innovative design prevents the stencil from warping or lifting (bulging) when heated during the reballing process, ensuring perfect alignment.
Hole Type: Features a high-precision pattern of apertures (holes) that are often Square Round Hole designed for accurate and consistent application of solder paste/balls.
Advantage: Deformation-resistant material and precise pin location for enhanced reliability.

Manufacturer Philosophy

Brand: AMAOE (阿毛易修®)

The CPUs listed (SC7727S, SC7730S, SC7731C, SC7715A, SC7731G, SC9832A, SC9830A, SC7730A, SC8830A, SC8825C, SC6825A, SC8825A) are all older entry-level or budget-category System-on-Chips (SoCs) manufactured by Spreadtrum (now known as UNISOC).

These chips were widely used globally in the following types of devices:

CPU IC Supporting Model Categories

Category	Typical Device Examples and Purpose	Key Chip Examples
Budget Android Smartphones (3G/4G)	Entry-level smartphones, often sold in developing markets. Used in devices focused on basic communication, browsing, and light social media.	SC7731C, SC7731G, SC9830A, SC9832A
Feature Phones (Smart/KaiOS)	Devices like the Nokia 3310 3G or other “smart feature phones” that require a low-power chipset with basic connectivity.	SC7731E (related to the 77xx series)
Budget Tablets (3G/4G Calling)	Inexpensive Android tablets, particularly those with SIM card slots supporting voice calling and mobile data.	SC7731 series, SC9832A
Wearable & IoT	Some of the smaller and lower-power chips in this family (like the SC7715A) were designed for basic connected devices, although they are primarily known for mobile use.	SC7715A
Older/Legacy Budget Models (2G/3G)	Very old or extremely low-cost devices from brands like Samsung (Galaxy Star, Galaxy J series), Huawei (Honor Bee), Lava, Intex, and other regional brands.	SC7727S, SC7730S, SC8825, SC8830

Specific Examples of Supported Devices (General)

Since the list is a collection of CPUs across many generations and markets, a comprehensive list is difficult, but the chips were used in devices such as:

Samsung: Galaxy J1 Mini Prime, Galaxy J3 (2016), Samsung Z1/Z2 (Tizen OS phones)
LYF: Flame 7, Flame 7s
Archos: Various Access and Neon series phones/tablets
Intex/Micromax/Lava: Various Aqua, Spark, and Bharat budget series phones
Various ODM/White-Label Devices: Numerous unbranded or regionally branded phones and tablets globally.

In summary, the AMAOE U-SCU1 stencil is a collective tool for technicians to repair the CPUs of a very large installed base of older, budget-friendly Android and 3G/4G calling tablet devices.

The U-SCU1 stencil is a master collection of patterns for many older, entry-level Spreadtrum/UNISOC chips, which were widely used globally in budget Android phones and tablets, often from regional or emerging brands.

Because these chips were used in hundreds of different, lower-cost models over several years, a single, exhaustive list is impractical. However, I can provide a list of common brands and specific examples associated with these chip series, particularly the more modern ones like SC983x and SC773x:

Specific Mobile Model Examples

Chip Model	Associated Mobile Models (Examples)	Brand Type	Connectivity
SC9832A	Intex Aqua series, Micromax Bharat 2, Archos Access 40, various Cherry Mobile and iVooMi phones.	Budget/Regional	4G LTE
SC9830A	Samsung Galaxy J1 mini Prime, Samsung Galaxy J3 (2016), LYF Flame 7 / 7s, Philips S326.	Budget/Mainstream	4G LTE
SC7731G / C / S	Samsung Galaxy J3 (2016) J320H/F (3G versions), Motorola Moto E (1st Gen) (some variants), various budget 3G tablets and phones (e.g., Tecno, itel).	Budget/Mainstream	3G
SC7727S / SC7715A	Older or very low-end smartphones and 3G feature phones from brands like Karbonn, Lava, and Spice.	Low-end/Regional	3G
SC88xx / SC68xx	Very old, often 2G/3G-only smartphones from the early-to-mid 2010s, typically used by regional Chinese and Indian manufacturers.	Legacy/Low-end	2G/3G

In short: If a technician needs to reball a CPU chip on a budget Android phone or tablet released roughly between 2014 and 2018 that supports 3G or basic 4G, and the CPU has the SPREADTRUM/UNISOC logo, this U-SCU1 stencil is likely the correct tool for the job.
