MINIMUM REQUIREMENTS

FOR A

PRINTED CIRCUIT BOARD DEFLUXING

3 Nov 15

GENERAL

This specification is for a complete automatic Printed Circuit Board (PCB) cleaning/defluxing system that has the ability to remove any kind types of flux residue from an assembled printed circuit board and provide a cleanliness level after the process has been completed.

The automatic cleaner/defluxer system shall be designed and built to meet the following minimum requirements:

1) Main System:

a. Shall have the ability of cleaning, rinsing, and drying the PCB with a zero discharge process to eliminate Electrostatic Discharge (ESD) damage to the PCB.

b. Shall have the ability to remove flux with the following chemistry types: Rosin, Water Soluble, and No Clean Flux.

c. Shall be able to support PCB with surface mount (SMT), through hole (THT), and mixed technologies type components.

d. Shall be compatible with Lead and Lead-Free alloy type solder.

e. The cleaning cycle shall go through at least three cycles:

i. Spray cycle consisting of applying a washing solution that softens the residues in the boards while it oscillates the boards in a PCB rack/tray.

ii. Rinse cycle consisting of removing the wash solution and contamination from the PCBs.

iii. Dry cycle consisting of using hot air to dry the PCBs.

f. Shall have a cleanliness tester that can tell how clean the PCBs are according to a pre-programmed cleanliness level and if it meets or exceeds this level.

g. Shall be able to determine the cleanliness of the water and the solution.

h. Shall have a minimum average cleaning cycle time of thirty minutes.

i. All this data, including all processed data in real time, shall be displayed and operated through at least a sixteen inch touchscreen display.

j. Control system shall be Windows 7 or at least Windows 7 compatible.

k. Shall be able to export data through USB.

l. Shall not require installation of drains for used chemicals and water.

m. Shall have an ESD Ground Point on the system.

n. Shall have a pre-drain filtration system to in order to remove used water and chemical solution.

o. Shall have water and chemical solution stainless steel tanks.

p. Chemical solution tank shall be a minimum of 12 gallons.

q. Shall be able to perform chemical dosing and mixing.

r. Chemical dosing and mixing (chemical management) tank shall have a minimum of 8 gallons stainless steel tank.

s. Shall have gauges either on the machine or through the display indicating the solution level and warnings for maintenance.

t. The dimensions shall not exceed (W x D x H):

i. 44” x 42.5” x 79”

ii. 28” x 38” x 50” for the rinse water recycling system for the main system.

u. Shall not exceed the weight of 791 lb.

v. Input power for the unit shall be 100 to 240 VAC at a frequency of 50-60 Hz, and at a current of 40 Amps.

2) Accessories:

a. A minimum of five gallons of concentrated defluxing chemical that meets the following:

i. Environmentally friendly

ii. Has a long tank life.

iii. Removes flux, including, but not limited to: Rosin, Water Soluble, and No

Clean Flux.

iv. Safe on delicate PCB substrates.

b. A stainless steel containment tray that fits underneath the cleaner to prevent floor damage if any leakage occurs.

c. One caster set in order to have the ability to move the system easily.

d. A minimum of ten, twenty micron filters that will fit the unit.

e. One handheld refractometer in order to measure the PH levels, purity, and concentration of the chemicals and water.

f. One barcode scanner to identify the barcodes in the boards in order to automatically load the cleaning program for that specific board.

g. Shall include cables and connectors for every port in the system.

3) Feeders:

a. One steel base mount with 32 port feeders that are compatible with the feeders.

i. The interface for the base mount shall have PS232 ports on it that will interface with the main computer and interact with their software.

b. One Universal IC Tube feeder with five different lanes for different ICs.

i. Each line shall be 8mm wide.

ii. Use RS232 communication.

iii. Take up five ports on the steel base mount.

c. Feeders shall use RS232 port communications.

i. Shall have programmable flash memory, in order to store part numbers and quantities of component parts.

ii. Shall be a maximum of seventeen inches long, not including the reel holder, and seven inches tall.

d. Four Tape Feeders for 8mm tapes with a maximum of 3.3 tape thickness.

e. Seventeen Tape Feeders for 8mm tapes with half-step advance, suitable for

0201/0402 components.

f. Three Tape Feeders for 12mm tapes with a maximum of 7mm tape thickness.

g. Three Tape Feeders for 16mm tapes with a maximum of 14mm tape thickness.

h. Two Tape Feeders for 24mm tapes with a maximum of 14mm tape thickness.

i. Two Tape Feeders for 32mm tapes with a maximum of 14mm tape thickness.

4) Software:

a. Ability to control and monitor the cleaner from a PC with a touchscreen display.

b. Shall be compatible with the Operating Systems of Windows XP and above, preferably Windows 7.

c. Shall be able to create and execute custom cleaning programs.

d. Shall be able to display data in real time.

The materials and component parts shall be of high commercial quality, with safety standards of

CSA, UL, and/or CE. As for the environmental standards, it shall comply with RoHS and/or WEEE.

Workmanship shall be consistent with best commercial practices.
