Our Process

Our Process: Preparation

Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.

Our Process: Receiving

Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.

Our Process: Initial Testing
Initial Testing

Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.

Our Process: Refurbishment

Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.

Our Process: Repair

Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.

Our Process: Final Testing
Final Testing

Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.

Our Process: Shipping

After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.

Accutek AK5816384S / AK5816384G 16,777,216 Word by 8 Bit CMOS Microcircuit Dynamic Random Access Memory Corporation DESCRIPTION Front View The Accutek AK5816384 high density memory module is a CMOS 30-Pin SIM DRAM organized in 16 Meg x 8 bit words. The assembly consists of eight 16 Meg x 1 DRAMs in plastic SOJ packages mounted to the front side of a printed circuit board in 30 pad SIM (leadless) or SIP (leaded) configuration. The module is only 0.8 inch high (same 1 30 height as standard 1 Meg modules), making it ideally suited for ap- plications with low height restrictions. 30-Pin SIP The operation of the AK5816384 is identical to eight 16 Meg x 1 DRAMs. The data input is tied to the data output and brought out separately for each device, with common RAS, CAS and WE con- trol. This common I/O feature dictates the use of early-write cycles 1 to prevent contention of D and Q. Since the Write-Enable (WE) sig- nal must always go low before CAS in a write cycle, Read-Write and Read-Modify-Write operation is not possible.
