# 🔧 Reflow Profile Board Tracking (PERN Stack)

This project was done as a part of my internship at Bharat FIH- a Foxconn technology group which is the largest EMS company group in India.

A full-stack application built using **PostgreSQL, Express.js, React.js, and Node.js (PERN)** for tracking reflow profiling of PCB boards across customers, models, storages, and board types.

## 📌 Features

- 🏠 **Home Page**: Overview/dashboard

- 🔍 **Profiler Page**:

  - Select customer, model, storage, and board type

  - Add row/column to the board type table

  - Save and update profile usage (with 80-use constraint) (kept 6 for simplicity)

  - Color indication for row changes (turns pink after 20 changes) (kept 3 for simplicity)

  - "Reuse" button to increment usage

  - Buttons: `New Profiler`, `History`, `Back`, `Reset`

- 📜 **History Page**:

  - Logs all profiling changes with timestamp

  - Displays profiling history by different profilers (P1, P2, P3)

  - Also displays reused logs

## 🧱 Tech Stack

- **Frontend**: React.js

- **Backend**: Node.js + Express.js

- **Database**: PostgreSQL

- **Version Control**: Git + GitHub

## 🗂️ Database Schema Overview

### Tables

- **Customer**

- **Model**

- **Storage**

- **BoardType**

- **Profiler**

- **ReflowTable**

   - have all previous table values, no-of-times-used and timestamp

- **History**

  - includes all changes that are made using the reflowtable, and any change in the no-of-times-used column has a separate entry in history

  - on retrieval, displayed based on timestamp 

---

## 🔁 Usage Constraints

- Each board type can be reused **up to 80 times**

- UI highlights row in **pink after 20 changes**

- After completion of 80 changes, row highlighted to **red**

- Each update is recorded in **History Table**
