Feature:
1.Embedded Industrial PC, high definition touch screen interface, PLC control, and instant profile analysis function. Real-time settings and actual temperature profile display can be used to analyzed and correct parameters if necessary.
2.It uses precise K-type close circuit control and automatic temperature adjustment system, with PLC and temperature module to enable precision temperature control of ±2 degC. External temperature sensor enables temperature monitoring and accurate analysis of real time temperature profile.
3.V-groove PCB support for rapid, convenience and accurate positioning that fits for all kinds of PCB board.
4.Flexible and convenient removable fixture on the PCB board which protectsand prevent damage to PCB. It can also adapt to rework various BGA packages.
5.Various sizes of BGA nozzles, which can be adjusted 360 degree for easy installation and replacement;
6. Three temperature areas can independently heat and are multiple controllable and adjustable to ensure best integration of different temperature areas. Heating temperature, time, angle, cooling and vacuuming can all be set on the interface.
7.There are 6-8 levels of variable and constant temperature controls. Massive storage of temperature curves which are Instant accessible according to different BGA. Curve analysis, setting and adjustment are all accessible via touch screen. Three heating areas adopts independent PID calculation to control heating process to enable more
8.accurate and precise temperature control.
9.It uses high powered blower to enable fast cooling of PCB board and prevent it from deformation. There are also internal vacuum pump and external vacuum pen to assist with fetching the BGA chip.
10.High precision digital video registration system, rocker to make the optical lenses move in forword/back and right/left. Observe the counterpoint of four corners of BGA and central point.
11.Including Voice "early warning" function. 5-10 seconds before the completion of uninstalling or welding, voice reminder / warning to get the workers prepared. Cooling system will start after vertical wind stopped heating. When the temperature drops to room temperature, the cooling process will stop, so that the machine will not age after heated up.
12.CE certification, with emergency switch and automatic power-off protection device when emergency happens
DH-A5主要性能与特点:
1、嵌入式工控电脑,高清触摸屏人机界面,PLC控制,并具有瞬间曲线分析功能. 实时显示设定和实测温度曲线,并可对曲线进行分析纠正。
2、高精度K型热电偶闭环控制和温度自动补偿系统,并结合PLC和温度模块实现对温度的精准控制,保持温度偏差在±2度.同时外置测温接口实现对温度的精密检测,并实现对实测温度曲线的精确分析和校对.
3、采用伺服运动控制系统,可实现焊接、贴装、拆卸三种模式自动化控制:稳定、可靠、安全、高效; PCB板定位采用V字型槽,采用线性滑座,使X、Y、Z三轴皆可作精细微调或快速定位、方便、准确,满足不同PCB板排版方式及不同大小PCB板的定位.
4、灵活方便的可移动式万能夹具对PCB板起到保护作用,防止PCB边缘器件损伤及PCB变形,并能适应各种BGA封装尺寸的返修.
5、配备多种规格合金风嘴,该风嘴可360度任意旋转定位,易于安装和更换;
6、上下共三个温区独立加热,三个温区可同时进行多组多段温度控制,保证不同温区同步达到最佳焊接效果。加热温度、时间、斜率、冷却、真空均可在人机界面上完成设置。
7、8段升(降)温+8段恒温控制,可海量存储温度曲线,随时可根据不同BGA进行调用,在触摸屏上也可进行曲线分析、设定和修正 ; 三个加热区采用独立的PID算法控制加热过程,
8、采用高精度数字视像对位系统,摇杆控制,可通过手动摇杆来控制光学镜头的前后左右移动,全方面的观测BGA 芯片的四角和中心点的对位状况,杜绝“观测死角”的遗漏问题。
