MET-STAG 5

STEAM AGEING CHAMBER

ACCELERATED STEAM AGEING TARGET is described in MIL STD 833 D and ANSI J STD – 002/003 as:

"Before parts are tested for solderability, require that they be exposed to steam for 8 hours, at 93°C" (at sea level)"

ANSI J – STD 003, described

3.3.1 Steam Ageing apparatus. Specimens to be steam aged shall be exposed to the saturated steam in a container constructed from borosilicate glass or stainless steel. The specimen holder shall be non-metallic and non reactive with moisture to prevent galvanic corrosion or holder degradation…. The steam temperature at the ageing level shall be maintained per the requirement of table 4."

"3.4.2 The ageing is intended for tin and tin/lead coatings only. All specimens identified as requiring steam ageing shall be subjected to accelerate ageing prior to solderability testing, by exposure of the surfaces to be tested to steam in the equipment specified in paragraph 3.1.1. The specimens shall be exposed to steam per table 4, for 8 hours +/- 15 minutes."

MET STAG 5 is specially designed to reproduce a saturated steam in a chamber, fitted with 5 drawers; Teflon static control coated.

The steam temperature is maintained very accurately by two thermocouples and controllers with Read out digital display (one thermocouple is immersed in the steam and the 2nd is immersed in the water).

MET STAG 5 is built up in stainless steel (3042) and all parts in contact with STEAM, are protected by special Teflon static control coating

DI (or distilled water) in the reservoir : 7 liters

DI (or distilled water) in the tank : 5 liters to automatically maintain the water level into the reservoir.

No need of external plumbing for water input.

 

5 drawers, dimensions each drawer: L 300 mm – H 50 mm – W 70 mm

Over all dimensions L 820 mm - W 480 mm - H 385 mm

Weight : 50 Kg

Power: 2000 W

MET-TOOL

LEADED SMD’S / SPECIAL BENDING TOOL

FOR SOLDERABILITY TESTER

 

 

Solderability test using a wetting balance tester Globule or solder bath – requires the need for leaded components such as SOIC, TQFP, SO, PQFP, SSOP, TSSOP etc . to

"remove sufficient leads to avoid bridging between tested leads".

International standards – CEI/IEC 68-2-69

Edition 1995-12

Environmental Testing

For this purpose, we have developed a special bending and forming tool providing the possibility to eliminate a selected raw of leads at various steps :

1,27 mm

1 mm

0,80 mm

0,65 mm

0,50 mm

0,40 mm

and any other steps upon special request.

The tool is fitted with a range of combs, fixed on a rotating drum, and the component is blocked very strongly in a cell, adjustable in X and Y axis, by micrometric screw.

Tool sizes : L 150 mm, W 90 mm H 80 mm
