Description

What Is a BGA SMT/SMD Reflow & Reball Machine?

Reflow Function: Uses precise hot air (top & bottom) and infrared heating zones to melt solder and attach BGA/SMD components to PCBs via controlled temperature profiles.
Reballing Function: Removes existing solder balls from a BGA chip, aligns a metal stencil, and places fresh solder spheres back onto the chip prior to reflow.

These combined machines are ideal in prototyping, component refurbishment, electronics repair labs, and production troubleshooting contexts.

Model: DH-A2

1. Application Of Automatic

Solder, reball, desoldering different kinds of chips: BGA,PGA,POP,BQFP,QFN,SOT223,PLCC,TQFP,TDFN,TSOP,

PBGA ,CPGA, LED chip.

Advantages & Features
1. Integrated Reflow & Reball in One Unit

Enables complete chip rework in one system: desoldering, stencil reballing, solder ball placement, vision alignment, and final reflow.

Offers workflow efficiency and lower equipment cost versus separate devices
2. Multi-Zone, Precise Thermal Control

Typical systems include 3 independent heating zones: top hot air, bottom hot air, and IR bottom pre‑heater.
Use of K‑type thermocouples and PID closed‑loop control ensures temperature accuracy within ±1 °C, mitigating PCB warpage and thermal damage.

3. High‑Precision Vision & Alignment

CCD optical systems (often with beam splitters or zoom) paired with laser positioning deliver placement accuracy around ±0.01 mm.
Stencil alignment in X/Y/t and theta control ensures accurate ball placement and reflow alignment.

4. User-Friendly UI With Profile Storage & Analysis

Many units provide touchscreen HMI, password-protected settings, profile memory (often saving hundreds of curves), and real-time graphing and analysis.
Ideal for novices and ensures repeatable, traceable process control

5. Efficient and Safe Operation

Automatic vacuum pickup heads, servo-controlled motion, and optional nitrogen purge help reduce voids and improve yield.
Safety features include over‑temperature alarms, automatic power‑off, ESD protection, voice alerts before welding, and cooling fans to speed cycle time and reduce PCB strain.

6. Broad Compatibility & Cost Savings

Supports a wide range of chip sizes (from ~1×1 mm to 80×80 mm) and fine-pitch BGAs (≥0.15 mm).
Enables salvaging of expensive chips (e.g., from smartphones, consoles, laptops), reducing need to replace whole boards - typical repair success rates exceed 98%–99%.

DIY Printed Circuit Board

Are you using a universal board to repair a circuit, but finding it difficult to achieve the circuit layout you need? For many electronics enthusiasts today, the universal board can no longer meet the demands of production. However, having a PCB made by manufacturers can be expensive-sometimes costing tens of dollars per board. So, is there a better option? The photosensitive plate offers a low-cost and convenient solution, allowing you to create complex or even patch circuits with high precision. In short, it's practical and easy to use, making it a great choice for DIY circuit boards!

To demonstrate, let's use a simple 20-piece "straw hat" LED parallel circuit as an example, and I'll show you how to take advantage of the photosensitive plate-it's neat, convenient, and easy to use!

Draw and Print Your Circuit Diagram!

First, you need to draw the circuit diagram. For this, I recommend using PCB design software like Sprint Layout. While you can use other software, I suggest Sprint Layout, especially for beginners, because it's simple and user-friendly.

Once your design is complete, you'll need to print the diagram. If you have a printer at home, great! If not, you can search for the "Smart Printer virtual printer crack version" on Baidu-this practical, green software allows you to convert any document into a variety of formats. You can then take the printed image to a print shop, avoiding the need to bring a .LAY file that most print shops can't open.

Print out the circuit diagram, and cut it to the size of your design!

Note: Carefully inspect the printed lines. Sometimes there might be breaks or short circuits. If you're using an inkjet printer, increase the line spacing slightly to avoid breaks. If any lines are broken, fill them in manually. If you spot any short circuits, adjust the line spacing and reprint the diagram.
