Hampshire based PCB Partners has placed an order for a Blundell System 2000 aqueous PCB cleaning machine.

After winning a new contract that requires daily use of a defluxing system and researching the market they decided that the Blundell System 2000 was the most economical choice.

Director Dave Maloney says: “The AEI/Esprit/Icon Group of which we are a part has worked closely with Blundell on other projects and we have always found their after care and maintanance to be first rate. This was a big factor in our decision.”

Reasons to clean printed circuit boards are as follows: (1) Reliability - cleaning removes all contaminants and prevents corrosion (2) For conformal coating - if the PCB is to be coated, all residues of flux need to be removed to prevent unseen corrosion taking place under the coating (3) for in-circuit testing, some test jigs with pins that contact the leads are affected by flux residues and form a bad connection if the PCB is not cleaned (4) for military, aerospace and high reliability applications cleaning is compulsory and is demanded by the end user.

The Blundell System 1000 and 2000 are aqueous PCB cleaning machines which are ideal for removing flux residues and general contamination from PCB’s. They are compact and well priced. Please contact us for details.

Interest in machines for cleaning printed circuit boards has noticeably increased in the past few months. It is generally recognised that the no-clean process is fine for some applications, but where high frequency electronics are used, or where conformal coating is applied, PCB’s need to be completely free of flux residue. The Blundell System 1000 and System 2000 are aqueous batch cleaning machines designed for cleaning small quantities of PCB’s using water and eco friendly saponifier. The purity of the final de-ionised water rinse is monitored so that cleanliness levels can be measured. The machine issues a print-out of the condition of the final rinse water as evidence of the cleanliness level achieved.

Aqueous cleaning is the safest and most cost effective way of cleaning assembled printed circuit boards (PCB’s). The latest environmentally friendly cleaning solutions are mixed with water to wash off flux residues, and the wash cycle is followed by a deionised water rinse, dehumidification and drying. The resultant cleanliness of the finished PCB is controlled by monitoring the quality of the waste water as it leaves the machine. The rinse cycle is automatically continued until the desired level of cleanliness is reached. No harmful solvents are used and each cleaning cycle uses only 3 litres of water. The machine used is the System 2000, and it is available from Blundell Production Equipment Ltd. For more information contact Paul or Neil Blundell on 0845 872 4975 (local call rates in the UK).
