Paggen: Reliably soldering large sample boards
Image: PaggenManySMEs and start-ups often face unsolvable challenges when creating prototypes if they have to solder large boards. Switching to contract manufacturers usually fails due to long delivery times and the purchase of a 'used' machine often fails due to the space required.
Paggen is now launching the HR30 based on the existing HR10 benchtop unit. The compact tabletop reflow oven offers all the functions required of a modern soldering device. Boards up to a size of 410 x 600 mm and components with a height of 55 mm at the top and 30 mm at the bottom can be soldered in the process chamber. An integrated fume extractor with 1500 l/h and 2 m exhaust air hose shortens the process times and is also part of the equipment, as is a connection for N2 with the associated control for soldering in an inert atmosphere. A connected load of 7800 W offers sufficient power reserves to realize even steep gradients. The soldering process itself is carried out using a combination of IR radiation and convection heat, which is gentle on components. Heat shields minimize the light-dark problem of IR radiation and ensure perfect heat transfer. The motorized door opening is programmable and starts the adjustable rotors of the powerful forced cooling system after the reflow process.
Programming via touch display and an automated process sequence ensure reliable operation of the system - regardless of whether linear or saddle profiles are to be created, the rise gradients changed, soldered with or without N2, or drying programs created. All parameters can be changed and controlled on the touch display. A total of seven measuring thermocouples (three permanently installed in the chamber and four freely positionable) enable seamless monitoring of the entire soldering process. The soldering profile and documentation of the process can be followed in real time via the USB interface. The MTPWIN software required for this is included in the scope of delivery and is supplied on a USB stick.
