ヒガシ電子工業 List of Products and Services

Here is a case of a request for repair of a PlayStation 4 power connector. The cable coming from the power supply unit is connected to the motherboard, but in this case, the connector was pulled out, causing it to detach along with the board pads and patterns. All pads (including reinforcement pads) were detached and came off with the connector. In this instance, since the power and ground remained on the board side, we only performed adhesion, while for the two signal lines, we transplanted the patterns and connected them. We also ensured continuity with a tester. 【Work Steps】 ■1. Remove the connector still attached to the power cable. ■2. Remove the pads that are still attached to the connector. ■3. Main work: reform the removed pads and restore them. ■4. Remove residual solder from the regenerated pads on the board. ■5. Solder the removed connector. ■6. Conduct a visual inspection and complete without issues. *For more details, please download the PDF or feel free to contact us.

• Other Connectors

Here is an introduction to a case where we received a request for WLCSP rework. WLCSP (Wafer Level Chip Size Package) is a package size equivalent to a bare chip called a die, and is considered one of the smallest levels in semiconductors. The requested component also has an outer dimension of 1.5mm and a pitch of 0.4mm. This time, we replaced the part that had been coated with a preservative, ensuring that there were no remnants left behind during the work. [Case Overview] ■ Content: Replacement of the part coated with a preservative ■ Outer Dimension: 1.5mm ■ Pitch: 0.4mm *For more details, please download the PDF or feel free to contact us.

• Chip type LED

Here is a case where we received a request for replacing vehicle parts with bullet-shaped LED lights. This time, the customer requested a color change (from orange to blue), so we carried out the replacement with the parts provided by the customer. We can handle this type of LED replacement if the customer disassembles the unit (in terms of the condition of the circuit board) and prepares the replacement parts. If you have any other concerns, please feel free to let us know. 【Work Procedure】 ■1. Remove the LED from the circuit board ■2. Remove the solder from the through-hole (TH) ■3. Main task: Install the new LED ■4. After adjustments, solder it in place and cut off any excess leads ■5. Finally, perform a lighting check to complete *For more details, please download the PDF or feel free to contact us.

• Printed Circuit Board

We would like to introduce a case where we received a request for LED replacement (vehicle parts: blind spot monitor). This time, the customer requested a color change (from orange to red), so we carried out the work in the following sequence: disassembly of the mirror → investigation of LED specifications, procurement → replacement. If you are unable to disassemble the unit (condition of the circuit board) or prepare replacement parts like in this LED replacement case, please feel free to consult us. If you have any other concerns, please let us know. 【Work Steps】 ■1. Remove the LED case from the mirror ■2. Disassemble the case (case, lens, circuit board) ■3. Main task, replace the LED ■4. Reassemble the disassembled case, lens, and circuit board ■5. Finally, perform a lighting check to complete *For more details, please download the PDF or feel free to contact us.

• Solder

We perform rework on various types of mounted components (SMD, IMD). We offer five patterns of service: "new component rework," "new component addition," "removal (live capture)," "component regeneration/re-implementation," and "component regeneration only." Additionally, we possess rework equipment from reliable domestic manufacturers, allowing us to measure and provide temperature profiles as needed. 【Rework Lineup for Mounted Components (partial)】 ■BGA ■QFP ■SOP ■PLCC ■HTD *For more details, please download the PDF or feel free to contact us.

• Circuit board design and manufacturing

At Higashi Electronic Industry Co., Ltd., we accept rework of various types of mounted components (SMD, IMD), including BGA (Ball Grid Array). By performing BGA reballing, it is possible to reuse components (reinstallation on different boards due to component depletion, failure analysis of individual components, failure analysis and reproducibility confirmation through component swap reinstallation, etc.). We can also handle the removal (live capture) of components other than BGA that you wish to reuse, as well as modifications to the circuit board. 【Supported Patterns】 ■1. New component rework ■2. New component post-installation ■3. Removal (live capture) ■4. Component regeneration/reinstallation ■5. Component regeneration only *For more details, please refer to the related links or feel free to contact us.

• Other electronic parts

We would like to introduce the "mass production" services offered by Higashi Electronic Industry Co., Ltd.
