Convection Batch Oven

A brief background and history of the X-Reflow306 LF-AC Full Convection Batch Oven:

The predecessor of this Batch Oven, built in the UK in the 1990s, was called JEM-310 and was designed primarily for soldering of SMT components to two layer PCB’s using leaded solder pastes.

In the United States, the ovens were sold by OK Industries and in the UK by a company called Reddish Electronics. With the progress of the SMT technologies (higher densities of components, use of multilayer boards etc.), it became obvious that higher mass assemblies needed more and more energy to bring the boards to reflow temperatures. Also, the desire to have the temperature uniformity of gas in the oven (air or nitrogen) within 15 to 20 degrees across the heating chamber led to continuous development of new models. JEM-310 was quickly followed by JEM-410 and SM500. Reddish ovens were called SM500 CXE and sold mainly in Europe. In 1998 Bokar’s X-Reflow305 oven entered the world market.

This was basically the SM500 CXE oven, built in UK on an OEM basis for Bokar International. This model, modified by Bokar International to outperform the SM500 ovens had the same proven, solid housing painted in blue/black Bokar colors (to distinguish it from the ovens marketed by the UK Company).

In total, several thousand of these ovens were sold worldwide, giving the users excellent and practically failure-free operation for many years. We at Bokar International still maintain and manufacture many replacement parts for the ovens from the generation of JEM-310 and later models. We can supply replacement heaters, top clam shell gaskets, thermocouples, etc. If anyone needs the replacement parts please e-mail

From 2007, Reddish Electronics could no longer manufacture Batch Ovens in the UK.

Bokar International purchased all the remaining stock of oven parts and started manufacturing the new, greatly improved X-Reflow306 LF and X-Reflow306 LF-AC ovens.

The new X-Reflow306 models kept only the best and well-proven mechanical body parts (including a large viewing window) and two independent front and back heaters from the X-Reflow305 and SM500. The internal mechanical parts were modernized to facilitate service (heater or thermocouple replacement).The human interface was greatly improved with the use of a modern keypad with added function keys. A highly informative process window (see below) shows what one will see on the oven display prior to running and during the program).

The internal electronics were completely redesigned to give superior control over power management for ideal oven performance and to give the oven administrator many new possibilities for pre-programming the oven the way he/she wants it to perform. Trying to compare the X-Reflow305 to the X-Reflow 306 is like comparing a dial-type phone to today’s iPhone (TM). Comments and wish lists for improvements from many users all over the world of the predecessors of the X-Reflow306 batch ovens were carefully analyzed by Bokar International engineers and most of them were incorporated into current ovens.
