电路板的铣刻、钻孔

加工的第一步是采用机械或者激光加工方式在电路板基材上制作导电电路。根据实际需要，可选用电路板刻制机，或者激光设备进行加工。

使用 LPKF ProtoMat 系列电路板刻制机进行电路板铣刻、钻孔

LPKF ProtoMat 系列电路板刻制机可高精度进行电路铣刻、钻孔。加工时间短、精度高，加工后的电路板可立即进行检测。此外，可用于各种用途，例如加工多层板、面板、壳体，以及更多其它应用。该系列设备中既包括供初级者使用的型号，也包括供经验丰富的专业人士使用的型号。

ProtoLaser 用于激光加工电路板

ProtoLaser 系列激光加工设备采用激光成型导电线路。可进行电路板分板，切割 LTCC 和半固化片，在 PTFE 和陶瓷基材上钻孔或钻微孔。采用激光技术加工，精度高，加工的电路图案可以非常复杂。能够加工数字和模拟电路，以及射频和微波板，电路板尺寸可达 229 x 305 mm 。可在 PET 膜、FR4、陶瓷和高频基材上成型电路。

化学和非化学孔金属化工艺

通孔金属化后，可实现多层板相互连通。经电路板刻制机钻孔后，可使用涂覆导电膏或者化学镀的方式实现电气连通。利用涂覆导电膏进行通孔金属化，使用 LPKF ProConduct 方式。桌面型电镀系统有 LPKF Contac 和 MiniContac， 是化学镀方式。

LPKF ProConduct 利用导电膏实现通孔金属化

LPKF ProConduct 不再在实验室中使用化学药液: 电路板采用涂覆导电膏的方式实现通孔金属化。利用真空吸附力使导电膏穿过过孔，并涂覆在孔壁上，然后在烘箱中进行固化。该工艺稳定可靠，操作简单。

LPKF 电镀孔金属化工艺 Contac 和 MiniContac

LPKF Contac 和 MiniContac 是以样品电路板制作和小批量生产为目的的电镀孔金属化方式。反向脉冲电镀技术保证沉铜厚度均匀，即使是小孔也能取得理想效果。该工艺也适用于生产多层电路板。LPKF Contac 可加工的电路板尺寸达 430 x 330 mm，MiniContac的加工尺寸可达 230 x 330 mm。

LPKF MultiPress 压制多层电路板

该桌面型设备可一次压合多达8层的多层电路板。压力、温度、压合时间可按照不同材料进行调节。设备内置有包含全部加工参数的压合程序，也可将新的参数存储在设备内。加工时间只需90分钟。

压合多层板

将多层电路板压合成一个多层板的第三步，将多种不同种类的电路板制成一个多层板需要合适的温度、压力、以及压合时间。LPKF MultiPress 可压制多达8层的多层板。

Applying Solder Resist Mask and Assembly print

Prior to assembly a solder resist mast is applied to prevent short circuits during the soldering process, and the assembly print to mark component locations. LPKF ProMask and ProLegend will perform this task in just a few steps by applying lacquer.

LPKF ProMask and ProLegend for Applying Solder Resist Mask and Assembly Print

The LPKF ProMask makes applying green solder resist masks easy and cost efficient. The surface finish ensures the components are safe during the soldering process. LPKF ProLegend will produce the assembly print, logos and markings. A laser printer prints the structures onto a transparency and a photochemical production process transfers it onto the previously applied lacquer.

LPKF ProtoPrint for Applying Soldering Paste

LPKF ProtoPrint is a system for manually applying soldering paste onto circuit boards. The system is very accurate and easy to use and compatible with stainless steel or polyimide film stencils. The stencils are stretched into a frame, aligned on the circuit board and coated with paste. The soldering paste printer is available in various models for pros and novices.

LPKF ProtoPlace for Assembly

Once the soldering paste has been applied the LPKF ProtoPlace will position the components on the surface of the circuit board. Accurate placement is key for an optimal contact: the circuit board is adjusted with micrometer screws before the component is placed on it. The pick and place system is available in various models for pros and novices.

LPKF ProtoFlow for SMD Reflow Soldering

Following assembly the circuit boards are soldered inside the LPKF ProtoFlow reflow oven. This process is compatible with both leaded and lead-free soldering pastes. The system can handle circuit boards up to 229 mm x 305 mm in size with a maximum temperature of 320°C. The soldering process can be split into five temperature phases and stored as a profile. LPKF ProtoFlow can also cure adhesive and conductive polymer. The oven is available in various models for pros and novices.

Applying Soldering Paste, Assembly and Curing

The final process step adds soldering paste to all component contact points. Components are then placed on the circuit board with pinpoint precision. Inside the SMD soldering oven the fusing soldering paste connects with the components. LPKF offers systems for applying soldering paste, assembly and reflow soldering for each of these three steps.

ProtoMat E33 - The entry level system

Barely larger than a size A3 sheet of paper: the LPKF ProtoMat E33 is an economical and compact circuit board plotter for machining circuit boards without wet chemicals.

The LPKF ProtoMat E33 will structure single- or double-sided circuit boards, drilling holes for through-plating, cutting individual boards from the base material and can even engrave front plates for housings.
